drm/i915/display: Program TRANS_VTOTAL from mode vtotal

Browse source

There are monitors being sensitive to MSA and end up
blanking out when we override Vtotal, DP transcoder
uses TRANS_VTOTAL to derive MSA VTotal. Avoid overriding
crtc_vtotal to 1 on platform which supports VRR Timing
generator and always program VTOTAL from mode timing in
transcoder timing paths.

--v2:
- Remove write to crtc_state->hw.adjusted_mode.crtc_vtotal
during intel_vrr_get_config. (Ankit)
- Fix merge conflicts.
