Nicholas Piggin bee4f891fe powerpc/perf: Fix disabling BHRB and instruction sampling 
commit ea142e590a upstream.

When the PMU is disabled, MMCRA is not updated to disable BHRB and
instruction sampling. This can lead to those features remaining enabled,
which can slow down a real or emulated CPU.

Fixes: 1cade527f6 ("powerpc/perf: BHRB control to disable BHRB logic when not used")
