[PATCH 3/3] drm/i915/vrr: s/intel_vrr_possible()/has_vrr_tg_timings()/

[Ville Syrjala <ville.syrjala@linux.intel.com>]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Several places in the VRR code are using intel_vrr_possible() as
an indication whether whether we should program the VRR timing
generator registers or not. While the implementation is correct
the function name is very confusing. Rename the function to
has_vrr_tg_timings(), and make it static as it's no longer needed
outside intel_vrr.c.
