Sumeet Pawnikar 3088bb7aad powercap: RAPL: fix invalid initialization for pl4_supported field 
commit d05b5e0baf upstream.

The current initialization of the struct x86_cpu_id via
pl4_support_ids[] is partial and wrong. It is initializing
"stepping" field with "X86_FEATURE_ANY" instead of "feature" field.

Use X86_MATCH_INTEL_FAM6_MODEL macro instead of initializing
each field of the struct x86_cpu_id for pl4_supported list of CPUs.
This X86_MATCH_INTEL_FAM6_MODEL macro internally uses another macro
X86_MATCH_VENDOR_FAM_MODEL_FEATURE for X86 based CPU matching with
appropriate initialized values.

[ Ricardo: I only kept TIGERLAKE, ALDERLAKE, and ALDERLAKE_L in
  pl4_support_ids as only these models are enumerated before this
  changeset. ]
