cpufreq: intel_pstate: Support Emerald Rapids OOB mode

Prevent intel_pstate from loading when OOB (Out Of Band) P-states mode is
enabled in Emerald Rapids.

The OOB identifying bits are same as for the prior generation CPUs
like Sapphire Rapids servers, so also add Emerald Rapids to the
intel_pstate_cpu_oob_ids[] list.
