This defines isa_mem_base on both 32 and 64 bits (it used to be 32 bits
only). This avoids a few ifdef's in later patches and potentially can
allow support for VGA text mode on 64 bits powerpc.

Use alloc_maybe_bootmem() which wraps the if (mem_init_done)

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.

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.
