PCI: add generic pcibios_resource_to_bus()
This replaces the generic versions of pcibios_resource_to_bus() and pcibios_bus_to_resource() in asm-generic/pci.h with versions that use pci_resource_to_bus() and pci_bus_to_resource(). The replacements are equivalent except that they can apply host bridge window offsets when the arch has supplied them by using pci_add_resource_offset(). Each arch can convert to using pci_add_resource_offset() individually by removing its device resource fixups from pcibios_fixup_bus() and supplying ARCH_HAS_GENERIC_PCI_OFFSETS. ARCH_HAS_GENERIC_PCI_OFFSETS can be removed after all have converted. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
