perf/x86/intel: Support hybrid PMU with multiple atom uarchs
The upcoming ARL-H hybrid processor contains 2 different atom uarchs
which have different PMU capabilities. To distinguish these atom uarchs,
CPUID.1AH.EAX[23:0] defines a native model ID which can be used to
uniquely identify the uarch of the core by combining with core type.
Thus a 3rd hybrid pmu type "hybrid_tiny" is defined to mark the 2nd
atom uarch. The helper find_hybrid_pmu_for_cpu() would compare the
hybrid pmu type and dynamically read core native id from cpu to identify
the corresponding hybrid pmu structure.
