MIPS: mm: BMIPS5000 has inclusive physical caches

[ Upstream commit dbfc95f98f ]

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.
