Subject: cpufreq: intel_pstate: Support Sapphire Rapids OOB mode
Patch-mainline: v5.19-rc1
Git-commit: bbd67f1b5a9449b090560ca5288aef0cfe623275
References: jsc#PED-849

Prevent intel_pstate to load when OOB (Out Of Band) P-states mode is
enabled in Sapphire Rapids. The OOB identifying bits are same as the
prior generation CPUs like Ice Lake servers. So, also add Sapphire
Rapids to intel_pstate_cpu_oob_ids list.
