MIPS: Reorganize Cavium OCTEON PCI support.
Move the cavium PCI files to the arch/mips/pci directory. Also cleanup comment formatting and code layout. Code from pci-common.c, was moved into other files. Signed-off-by: David Daney <ddaney@caviumnetworks.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
