powercap: intel_rapl: Consolidate PL4 and PMU support flags into rapl_defaults
Currently, PL4 and MSR-based RAPL PMU support are detected using
separate CPU ID tables (pl4_support_ids and pmu_support_ids) in the
MSR driver probe path. This creates a maintenance burden since adding
a new CPU requires updates in two places: the rapl_ids table and one
or both of these capability tables.
Consolidate PL4 and PMU capability information directly into
struct rapl_defaults by adding msr_pl4_support and msr_pmu_support
flags. This allows per-CPU capability to be expressed in a single
place alongside other per-CPU defaults, eliminating the duplicate
CPU ID tables entirely.
No functional changes are intended.
