possible to make Chromebooks and other board types to coexist

The "regulator-compatible" property has been deprecated since 2012 in
commit 13511def87 ("regulator: deprecate regulator-compatible DT
property"), which is so old it's not even mentioned in the converted
regulator bindings YAML file. It should not have been used for new
submissions such as the MT6315.
Drop the "regulator-compatible" property from the board dts. The
property values are the same as the node name, so everything should
continue to work.

The RT5682i and RT5682s drivers describe two DAIs: AIF1 supports both
playback and capture, while AIF2 supports capture only.
Cherry doesn't specify which DAI to use. Although this doesn't cause
real issues because AIF1 happens to be the first DAI, it should be
corrected:
codec@1a: #sound-dai-cells: 1 was expected
Update #sound-dai-cells to 1 and adjust DAI link usages accordingly.

xhci1 has both USB 2.0 and USB 3.0 host capabilities. By default both
are assumed to be enabled when the controller is enabled. To disable
either one, an extra property is used.
Since the default has both enabled, both PHYs should also be assigned
to the host controller. If a specific design uses only either one,
the board specific dts file can override the PHY assignment together
with adding the "mediatek,u[23]p-dis-msk" property. This keeps both
changes together.

The MT8195 SoC has four USB controllers: only one is a direct path to
a XHCI controller, while the other three (0, 2 and 3) are behind the
MTU3 DRD controller instead!
Add the missing MTU3 nodes, default disabled, for controllers 0, 2 and
3 and move the related XHCI nodes to be children of their MTU3 DRD to
correctly describe the SoC.
In order to retain USB functionality on all of the MT8195 and MT8395
boards, also move the vusb33 supply and enable the relevant MTU3 nodes
with special attention to the MT8195 Cherry Chromebook, where it was
necessary to set the dr_mode of all MTU3 controllers to host to avoid
interfering with the EC performing DRD on its own.

The cros_ec driver currently assumes that cros-ec-spi compatible device
nodes are a wakeup-source even though the wakeup-source property is not
defined.
Some Chromebooks use a separate wake pin, while others overload the
interrupt for wake and IO. With the current assumption, spurious wakes
can occur on systems that use a separate wake pin. It is planned to
update the driver to no longer assume that the EC interrupt pin should
be enabled for wake.
Add the wakeup-source property to all cros-ec-spi compatible device
nodes to signify to the driver that they should still be a valid wakeup
source.

There is one new SoC for each 32-bit Arm and 64-bit RISC-V, but both
the Rockchips rv1109 and Sopgho CV1812H are just minor variations of
already supported chips.
The other six new SoCs are all part of existing arm64 families, but
are somewhat more interesting:
- Samsung ExynosAutov920 is an automotive chip, and the first one
we support based on the Cortex-A78AE core with lockstep mode.
- Google gs101 (Tensor G1) is the chip used in a number of Pixel phones,
and is grouped with Samsung Exynos here since it is based on the same
SoC design, sharing most of its IP blocks with that series.
- MediaTek MT8188 is a new chip used for mid-range tablets and Chromebooks,
using two Cortex-A78 cores where the older MT8195 had four of them.
- Qualcomm SM8650 (Snapdragon 8 Gen 3) is their current top range
phone SoC and the first supported chip based on Cortex-X4, Cortex-A720
and Cortex-A520.
- Qualcomm X1E80100 (Snapdragon X Elite) in turn is the latest
Laptop chip using the custom Oryon cores.
- Unisoc UMS9620 (Tanggula 7 series) is a 5G phone SoC based on
Cortex-A76 and Cortex-A55
In terms of boards, we have
- Five old Microsoft Lumia phones, the HTC One Mini 2, Motorola Moto
G 4G, and Huawei Honor 5X/GR5, all based on Snapdragon SoCs.
- Multiple Rockchips mobile gaming systems (Anbernic RG351V,
Powkiddy RK2023, Powkiddy X55) along with the Sonoff iHost Smart
Home Hub and a few Rockchips SBCs
- Some ComXpress boards based on Marvell CN913x, which is the
follow-up to Armada 7xxx/8xxx.
- Six new industrial/embedded boards based on NXP i.MX8 and i.MX9
- Mediatek MT8183 based Chromebooks from Lenovo, Asus and Acer.
- Toradex Verdin AM62 Mallow carrier for TI AM62
- Huashan Pi board based on the SophGo CV1812H RISC-V chip
- Two boards based on Allwinner H616/H618
- A number of reference boards for various added SoCs from Qualcomm,
Mediatek, Google, Samsung, NXP and Spreadtrum
As usual, there are cleanups and warning fixes across all platforms as
well as added features for several of them.

In cherry projects, we use edptx as the internal display interface
and use dptx as the external display interface. To support this, we
need to add more properties.
- Add pinctrls for edptx and dptx.
- Add ports for edptx and dptx.
The port connections for the internal and external display:
dp-intf0 -> edptx -> panel
dp-intf1 -> dptx
The edptx endpoint is kept empty for now, as the panel addition will
come in a later commit.
