arm64: dts: rockchip: enable PCIe on ROCK 4D

Browse Source 
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.
