KVM: x86/pmu: Add a helper to enable bits in FIXED_CTR_CTRL

Browse source

Add a helper, intel_pmu_enable_fixed_counter_bits(), to dedup code that
enables fixed counter bits, i.e. when KVM clears bits in the reserved mask
used to detect invalid MSR_CORE_PERF_FIXED_CTR_CTRL values.

No functional change intended.
