My main concern was this produces a big diff which would make it difficult for review. And CONFIG_PCIE_RCAR_HOST by default selects CONFIG_PCIE_RCAR which builds the host driver.
pcie-rcar.c is the same as mainline only that pcie-rcar-host.c is untouched here.
If you are OK ill post the similar changes to pcie-rcar-host.c as done in the actual upstream patch.

I shall get on posting the 2nd bunch of non-RFC.
