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[].
