Much like the Sige5, the ROCK 4D also has an HDMI port, so is capable of
providing HDMI audio output as well.
Enable the SoC's hdmi_sound card, and also enable the SoC audio
controller (sai6) that feeds into it.

The production version of the ROCK 4D appears to sport a AICSEMI
AIC8800D80 USB Wi-Fi + BT chipset. This chip does not yet have a
mainline driver.
Add the necessary rfkill node and wifi regulator node to at least make
it show up in lsusb output. The regulator is set as always-on, as like 2
hours deep into debugging why onboard_usb_dev.c wouldn't try enabling
the regulator the device needs to actually show up and thus bind to
onboard_usb_dev.c, I decided that it's not worth the effort.

The ROCK 4D uses both USB controllers, and both of which in host mode.
However, it still names one of the supplies for them "OTG" in the
schematic.
Fix the "host" supply's input, and add the "otg" supply. Enable the
remaining USB PHY nodes, and the first controller node as well.

The ROCK 4D's actual DC input is 5V, and the schematic names it as being
5V as well.
Rename the regulator, and change the voltage it claims to be at.
Furthermore, fix vcc_1v1_nldo_s3's vin-supply as coming from
vcc_5v0_sys, and not the DCIN, as per the schematic. This makes no
functional change; both regulators are always on, and one feeds into the
other.

Old revisions of the ROCK 4D board have a dedicated crystal to
supply the RTL8211F PHY's 25MHz clock input. At least some newer
revisions instead use REFCLKO25M_GMAC0_OUT. The DT already has
this half-prepared, but there are some issues:
1. The DT relies on auto-selecting the right PHY driver, which
requires that it works good enough to read the ID registers.
This does not work without the clock, which is handled by
the PHY driver. By updating the compatible to contain the
RTL8211F IDs, so that the operating system can choose the
right PHY driver without relying on a pre-powered PHY.
2. Despite the name REFCLKO25M_GMAC0_OUT could also provide a
different frequency, so ensure it is explicitly set to 25
MHz as expected by the PHY.
3. While at it switch from deprecated "enable-gpio" to standard
"enable-gpios".

The RADXA ROCK 4D board has a PCIe controller connected to a flat flex
connector, compatible with the one the RPi5 uses.
Enable the associated combphy and pcie controller node, as well as add
the remaining pinctrl definition for the reset.

The SPI NOR chip is connected on the FSPI0 core, so enable the sfc0 node
and add the flash device to it.
The SPI NOR won't work at higher speed than 50 MHz, specify the limit.

The Radxa ROCK 4D board is based on the Rockchip rk3576 SoC.
The device tree adds support for basic devices:
- UART
- SD Card
- Ethernet
- USB
- RTC
It has 4 USB ports but only 3 are usable as the top left one is used
for maskrom.
It has a USB-C port that is only used for powering the board.
