[PATCH 13/27] drm/i915/vrr: Introduce VRR mode Fixed RR

[Ankit Nautiyal]

VRR timing generator can be used even with fixed refresh rate.
With this the legacy timing generator can be phased out and VRR timing
generator can be used for all cases, whether panels support VRR or not.

Add an enum value to represent the VRR timing generator in
fixed refresh rate mode and update the helper vrrtg_mode_str
for printing it.
