MIPS: cpu-features: Enable octeon_cache by cpu_type
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.
