[PATCH] PCI: Constify dummy pci_register_io_range() fwnode_handle

[Geert Uytterhoeven <geert+renesas@xxxxxxxxx>]

If CONFIG_PCI=n:

    drivers/of/address.c: In function ‘of_pci_range_to_resource’:
    drivers/of/address.c:247:45: error: passing argument 1 of ‘pci_register_io_range’ discards ‘const’ qualifier from pointer target type [-Werror=discarded-qualifiers]
      247 |                 err = pci_register_io_range(&np->fwnode, range->cpu_addr,
	  |                                             ^~~~~~~~~~~
    In file included from drivers/of/address.c:12:
    include/linux/pci.h:2022:63: note: expected ‘struct fwnode_handle *’ but argument is of type ‘const struct fwnode_handle *’
