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.
