PCI: Convert pci_resource_to_user() to a weak function

Convert pci_resource_to_user() to a weak function so the existing
architecture-specific implementations will automatically override the
generic one.  This allows us to remove HAVE_ARCH_PCI_RESOURCE_TO_USER
definitions and avoid the conditional compilation for this single function.
