With GuC based SLPC, frequency control will be moved to GuC and Host will
continue to control RC6 and LLC ring frequency setup. This needs separate
handling of RPS, RC6 and LLC ring frequencies in i915 flows. We still
continue use the *gt_powersave routines with separate status variables
for RPS, RC6, ring frequency as pm.rps.enabled, pm.rc6.enabled and
pm.llc_pstate.configured respectively in dev_priv.
Post this, with SLPC changes integrated we can just skip the Host RPS path
in i915 PM flows.
v2: Added new patch 2. Addressed review comments. Pending review for last
3 patches and patch 2 currently.
