[PATCH 21/23] drm/i915/psr: Allow PSR for fixed refrsh rate with VRR TG

[Ankit Nautiyal]

At the moment PSR/PSR2 are not supported with variable refresh rate.
However it can be supported with fixed refresh rate while running with
VRR timing generator.
Enable PSR for fixed refresh rate when using the VRR timing generator.
