drm/i915/hdmi: Use VRR Timing generator for HDMI for fixed_rr

Browse Source 
Currently VRR is not supported with HDMI, but we can still leverage
the VRR Timing Generator to achieve a fixed refresh rate.
Call intel_vrr_compute_config() for HDMI which will handle the vrr
timings to have fixed refresh rate with VRR Timing Generator.

v2: Improve commit message. (Ville).
