As specified in the comment for pci_remap_cfgspace() define in
arch/arm64/include/asm/io.h file, PCIe configuration space should be
mapped as nGnRnE. Hence changing to dev_pci_remap_cfgspace() from
devm_ioremap_resource() for mapping DBI space as that is nothing but
the root port's own configuration space.
