The register and range mappings for the PCIe controller in Rockchip's
RK356x SoCs are incorrect. Replace them with corrected values from the
vendor BSP sources, updated to match current DT schema.

Hi, Andrew

This patch broken pcie3x2 on my board.
And the wireless card on pcie2x1 is still not working.

That's because 32bit mapping for pcie3x2 config should start at 0xf0000000 and
the patch declares it incorrectly at 0xf2000000.

That's ENOSPC. Who knows where it's comming from. Something for you to debug. ;)
