PCI: spear13xx: Update PCI config space remap function
PCI configuration space should be mapped with a memory region type that generate on the CPU host bus non-posted write transations. Update the driver to use the devm_pci_remap_cfg* interface to make sure the correct memory mappings for PCI configuration space are used.
