[PATCH v2 12/22] PCI: rockchip: update PCI config space remap function

[Lorenzo Pieralisi]

PCI configuration space should be mapped with a memory region type that
generates on the CPU host bus non-posted write transations. Update the
driver to use the devm_ioremap_nopost* interface to make sure the correct
memory mappings for PCI configuration space are used.
