PCI: Add fwnode handler as input param of pci_register_io_range()

Browse Source 
In preparation for having the PCI MMIO helpers use the new generic I/O
space management (logical PIO) we need to add the fwnode handler as an
extra input parameter.

Changes the signature of pci_register_io_range() and its callers as
needed.
