Successfully used this on an ArmSoM Sige5 RK3576 board. PCIe works.
Properties look correct, though the `ranges = ` doesn't separate out the
different ranges into individual `<cells>` but this doesn't seem to make
any difference and doesn't cause any warnings either. The only added
warning is "simple-bus unit address format error" which seems like a
bug in the thing generating the warning and not the device-tree itself,
as it doesn't seem to notice that the address of the node is within the
regs array, just not as the first cell.
I think this looks good for merging, I'll also send out a Sige5 enablement
patch shortly.
Thank you!

Nicolas Frattaroli
