arm64: dts: rockchip: fix nEXTRST on SOQuartz

In pre-production prototypes (of which I only know one person
having one, Peter Geis), GPIO0 pin A5 was tied to the SDMMC
power enable pin on the CM4 connector. On all production models,
this is not the case; instead, this pin is used for the nEXTRST
signal, and the SDMMC power enable pin is always pulled high.

Since everyone currently using the SOQuartz device trees will
want this change, it is made to the tree without splitting the
trees into two separate ones of which users will then inevitably
choose the wrong one.

This fixes USB and PCIe on a wide variety of CM4IO-compatible
boards which use the nEXTRST signal.

arm64: dts: rockchip: Enable PCIe 2 on SOQuartz CM4IO

This patch enables the PCIe2 on the CM4IO board when paired with

enabled in this case to make the PHY work for this.
