Despite what the code comments said, the DTS files were not split properly.
Since these two SoCs are now known to have minor differences like in
latencies for cpufreq state transistions, split the DTS files now.

This adds device trees for the following devices:
- Macbook Air (M2, 2022)
- Macbook Pro 13" (M2, 2022)
- Mac mini (M2, 2023)
This brings the hardware support of the machines to the same level as M1
and M1 Pro / Max / Ultra. Supported hardware include NVMe, PCIe, serial,
pinctrl/gpio, I2C, iommu, watchdog, admac, nco, cpufreq, boot
framebuffer for laptop panels and the interrupt controller.
The ethernet LAN device on the M2 Mac mini is the only working PCIe
device. The Wlan/BT devices are powered off and controlled by the not
yet supported SMC. The ASMedia xHCI on the M2 Mac mini requires firmware
to be loaded at startup.
The main missing hardware support to make these devices useful are the
integrated USB 2/3/4 controller, keyboard and trackpad on the laptops
and SMC to power the PCIe Wlan/BT device on.
The M2 Mac mini has currently no working display output. Due to changes
in the display pipeline it is currently not possible to initialize the
HDMI output in the bootloader.

On t6002 (M1 Ultra), each die contains a self-contained GPU block.
However, only the coprocessor and global management circuitry of the
first die are used. This is what is represented by the "gpu" PS (the
one in die1 is disabled). Nonetheless, this shared component drives the
processing blocks in both dies, and therefore depends on the AFR fabric
being powered up on both dies.
Add an explicit dependency from the GPU block on die0 to AFR on die1,
next to the existing die0 AFR dependency.

The t8103 CPU nodes are missing the cache hierarchy information. The
cache hierarchy on Arm can not be detected and needs to be described in
DT. The OS scheduler can make use of this information for scheduling
decisions.
The cache size information is based on various articles about the
processors. There's also an L3 system level cache (SLC). It's not
described here because SLCs typically have some MMIO interface which
would need to be described.
Based on Rob Herring's patch adding cache properties and nodes for
t600x.

The SIO_ADMA is a power domain of the Audio DMA Controller. In addition
to it, the AUDIO_P domain must be on for the controller's MMIO registers
to be accessible.
On t600x and t8112, AUDIO_P is a parent of SIO_ADMA. On t8103, it isn't
so, at least as far as Apple's firmware goes. To make our life easier,
add the parent-child relationship on t8103 also.

These SoCs are found in Apple devices with M1 Pro (t6000), M1 Max
(t6001) and M1 Ultra (t6002).
t6000 is a cut-down version of t6001, so the former just includes the
latter and disables the missing bits (This is currently just one PMGR
node and all of its domains.
t6002 is two connected t6001 dies. The implementation seems to use
t6001 with blocks disabled (mostly on the second die). MMIO addresses on
the second die have a constant offset. The interrupt controller is
multi-die aware. This setup can be represented in the device tree with
two top level "soc" nodes. The MMIO offset is applied via "ranges" and
devices are included with preproceesor macros to make the node labels
unique and to specify the die number for the interrupt definition.
Device nodes are distributed over dtsi files based on whether they are
present on both dies or just on the first die. The only execption is the
NVMe controller which resides on the second die. Its nodes are in a
separate file.

As usual, this is the bulk of the updates for the SoC tree, adding
more devices to existing files, addressing issues from ever improving
automated checking, and fixing minor issues.
The most interesting bits as usual are the new platforms.
All the newly supported SoCs belong into existing families
this time:
- Qualcomm gets support for two newly announced platforms, both
of which can now work in production environments: the SDX65
5G modem that can run a minimal Linux on its Cortex-A7 core,
and the Snapdragon 8 Gen 1, their latest high-end phone SoC.
- Renesas adds support for R-Car S4-8, the most recent automotive
Server/Communication SoC.
- TI adds support for J721s2, a new automotive SoC in the K3
family.
- Mediatek MT7986a/b is a SoC used in Wifi routers, the latest
generation following their popular MT76xx series. Only basic
support is added for now.
- NXP i.MX8 ULP8 is a new low-power variant of the widespread
i.MX8 series.
- TI SPEAr320s is a minor variant of the old SPEAr320 SoC that
we have supported for a long time.
New boards with the existing SoCs include
- Aspeed AST2500/AST2600 BMCs in TYAN, Facebook and Yadro servers
- AT91/SAMA5 based evaluation board
- NXP gains twenty new development and industrial boards for their
i.MX and Layerscape SoCs
- Intel IXP4xx now supports the final two machines in device tree
that were previously only supported in old style board files.
- Mediatek MT6589 is used in the Fairphone FP1 phone from 2013,
while MT8183 is used in the Acer Chromebook 314.
- Qualcomm gains support for the reference machines using the two
new SoCs, plus a number of Chromebook variants and phones based
on the Snapdragon 7c, 845 and 888 SoCs, including various
Sony Xperia devices and the Microsoft Surface Duo 2.
- ST STM32 now supports the Engicam i.Core STM32MP1 carrier board.
- Tegra now boots various older Android devices based on 32-bit
chips out of the box, including a number of ASUS Transformer
tablets.
There is also a new Jetson AGX Orin developer kit.
- Apple support adds the missing device trees for all the remaining

At the moment, all the Minis running Linux have the same MAC
address (00:10:18:00:00:00), which is a bit annoying.
Expose the PCI node corresponding to the Ethernet device, and
declare a 'local-mac-address' property. The bootloader will update
it (m1n1 already has the required feature). And if it doesn't, then
the default value is already present in the DT.
This relies on forcing the bus number for each port so that the
endpoints connected to them are correctly numbered (and keeps dtc
quiet).

PCIe on the Apple M1 (aka t8103) requires the use of IOMMUs (aka
DARTs). Add the three instances that deal with the internal PCIe
ports and route each port's traffic through its DART.

Add node corresponding to the apcie,t8103 node in the
Apple device tree for the Mac mini (M1, 2020).
Power domain references and DART (IOMMU) references are left out
at the moment and will be added once the appropriate bindings have
been settled upon.

This currently supports:
* SMP (via spin-tables)
* AIC IRQs
* Serial (with earlycon)
* Framebuffer
A number of properties are dynamic, and based on system firmware
decisions that vary from version to version. These are expected
to be filled in by the loader.
