microblaze/pci: Move the remains of pci_32.c to pci-common.c
There's no point in keeping this separate. Even if microblaze grows a 64-bit variant, it will probably be able to re-use that code as-is Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Acked-by: Michal Simek <monstr@monstr.eu> Acked-by: Grant Likely <grant.likely@secretlab.ca>
