This adds a function that tells you if a given kernel virtual address
is hitting a PCI or ISA IO port permanent mapping or not. This is to
be used in the next patch to fix iomap APIs to properly unmap things.

This fixes the fallout from the recent powerpc merge (commit
489de30259e667d7bc47da9da44a0270b050cd97):
CC arch/powerpc/kernel/pci-common.o
arch/powerpc/kernel/pci-common.c:160: error: conflicting types for 'pcibios_add_platform_entries'
include/linux/pci.h:889: error: previous declaration of 'pcibios_add_platform_entries' was here

Use the ppc64 style list management and allocation functions for
pci_controllers. This makes the pci_controller structs just a bit more
common between ppc32 & ppc64.

Moved the low hanging fruit that was either identical or close
to it between ppc32 & ppc64 for PCI into pci-common.c

Make the pci_controller struct use global_number for the PHB domain number
instead of index to match what ppc64 does and reuse its pci_domain_nr code.
Introduced a pci-common.c to handle shared code between ppc32 & ppc64.
