cpufreq: intel_pstate: Add Diamond Rapids OOB mode support

Browse Source 
Prevent intel_pstate from loading when Out-of-Band (OOB) P-states mode
is enabled.

The OOB identification mechanism for Diamond Rapids servers is the same
as for prior generation CPUs such as Granite Rapids. Add the Diamond
Rapids CPU model to intel_pstate_cpu_oob_ids[] to ensure correct OOB
handling.
