MIPS: Octeon: Move some platform device registration to its own file.
There is a bunch of platform device registration in arch/mips/cavium-octeon/setup.c. We move it to its own file in preparation for adding more platform devices. Signed-off-by: David Daney <ddaney@caviumnetworks.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
