MIPS: cpu-features: Enable octeon_cache by cpu_type

Browse source 
[ Upstream commit f641519409a73403ee6612b8648b95a688ab85c2 ]

cpu_has_octeon_cache was tied to 0 for generic cpu-features,
whith this generic kernel built for octeon CPU won't boot.

Just enable this flag by cpu_type. It won't hurt orther platforms
because compiler will eliminate the code path on other processors.
