Intel-SIG: commit b8c4d1a8 perf/x86/intel: Factor out intel_pmu_check_num_counters
Backport as a dependency for Sierra Forrest core PMU support.

-------------------------------------

Each Hybrid PMU has to check its own number of counters and mask fixed
counters before registration.

The intel_pmu_check_num_counters will be reused later to check the
number of the counters for each hybrid PMU.
