-------------------------------------------------

Intel-SIG: commit e97a98238da6 cpufreq: intel_pstate: Use __ro_after_init for three variables.
Backport intel_pstate driver update for 6.6 from 6.11

There are at least 3 variables in intel_pstate that do not get updated
after they have been initialized, so annotate them with __ro_after_init.
