local_r4k___flush_cache_all() is missing a special check for BMIPS5000
processors, we need to blast the S-cache, just like other MTI processors
since we have an inclusive cache. We also need an additional __sync() to
make sure this is completed.
Fixes: d74b0172e4e2c ("MIPS: BMIPS: Add special cache handling in c-r4k.c")
