perf/x86/rapl: Get quirk state from new probe framework
Browse files Browse the repository at this point in the history
Getting the apply_quirk bool from new rapl_model_match array.

And because apply_quirk was the last remaining piece of data
in rapl_cpu_match, replacing it with rapl_model_match as device
table.

The switch to new perf_msr_probe detection API is done.
