[PATCH] MIPS: Add CPU identifiers and probing for Cavium CN73xx and CNF75xx processors.

[PATCH] MIPS: Add CPU identifiers and probing for Cavium CN73xx and CNF75xx processors.

[David Daney]

From: David Daney <david.daney@cavium.com>

Add new processor identifiers for Cavium CN73xx and CNF75xx
processors, and probe for them in cpu-probe.c

Signed-off-by: David Daney <david.daney@cavium.com>

The kernel needs some follow-on changes to support these processors,
but this is an essential starting point.
