PCI: Add arch_can_pci_mmap_io() on architectures which can mmap() I/O space

This is relatively esoteric, and knowing that we don't have it makes life
easier in some cases rather than just an eventual -EINVAL from
pci_mmap_page_range().

PCI: Unify pci_resource_to_user() declarations

Replace the pci_resource_to_user() declarations in each arch that defines

Change the MIPS static inline implementation to a non-inline version so the
static inline doesn't conflict with the new non-static linux/pci.h
declaration.

Move this header, pci-dma-compat.h, to include/linux and include it from

PCI: MicroBlaze: convert pcibios_set_master() to a non-inlined function

This patch converts MicroBlaze's architecture-specific
'pcibios_set_master()' routine to a non-inlined function. This will
allow follow on patches to create a generic 'pcibios_set_master()'
function using the '__weak' attribute which can be used by all
architectures as a default which, if necessary, can then be over-
ridden by architecture-specific code.

Converting 'pci_bios_set_master()' to a non-inlined function will
allow MicroBlaze's 'pcibios_set_master()' implementation to remain
architecture-specific after the generic version is introduced and thus,
not change current behavior.

No functional change.
