MIPS: mm: BMIPS5000 has inclusive physical caches
[ Upstream commit dbfc95f98f0158958d1f1e6bf06d74be38dbd821 ] When the BMIPS generic cpu-feature-overrides.h file was introduced, cpu_has_inclusive_caches/MIPS_CPU_INCLUSIVE_CACHES was not set for BMIPS5000 CPUs. Correct this when we have initialized the MIPS secondary cache successfully.
