cpufreq: intel_pstate: Add more out-of-band IDs
Browse files Browse the repository at this point in the history
Add Skylake-X and Broadwell-X IDs for out-of-band (OBB) control of
P-States.

For these processors, if MSR_MISC_PWR_MGMT BIT(8) == 1, then the
Intel P-State driver should exit as OS can't control P-States.
