Subject: cpufreq: intel_pstate: Support Granite Rapids and Sierra Forest OOB
mode
Prevent intel_pstate from loading when OOB (Out Of Band) P-states mode is
enabled.
The OOB identifying bits are same as for the prior generation CPUs like
Emerald Rapids servers. Add Granite Rapids and Sierra Forest CPU models to
intel_pstate_cpu_oob_ids[].
