When we use different rps events for different platform or due to wa, we
mgiht end up doing (vs) everywahere. Insted of this, Let's use a variable
in dev_priv to track the enabled PM interrupts

I think we need to initialize pm_rps_events somewhere earlier since we
depend on it already in irq postinstall. Othwewise the patch looks
good.
Adding it in functions "intel_uncore_early_sanitize" or "pm_init" as
this gets executed before irq_install in driver_load?
