[PATCH PATCH v2 3/9] perf/x86/intel: Use topology_hw_cpu_type()

[Pawan Gupta]

get_this_hybrid_cpu_type() misses a case when cpu-type is populated
regardless of X86_FEATURE_HYBRID_CPU. This is particularly true for hybrid
variants that have P or E cores fused off.

Instead use topology_hw_cpu_type() as it does not rely on hybrid feature to
enumerate cpu-type. This can also help avoid the model-specific fixup
get_hybrid_cpu_type().
