Revert PCI rockchip changes that weren't merged upstream

Some PCI rockchip changes from a previous merged changed were dropped/not included upstream in v5.13. This is explained on this post: https://lore.kernel.org/linux-pci/20210614230457.752811-1-punitagrawal@gmail.com/

This MR reverts those changes. A diff between drivers/pci/of.c of upstream and ARK is clean now.
