Compute params for Adaptive Sync SDP when Fixed Average Vtotal
mode is enabled.
--v2:
Since vrr.enable is set in case of cmrr also, handle accordingly(Ankit).
--v3:
- Since vrr.enable is set in case of cmrr also, handle
accordingly(Ankit).
- check cmrr.enable when CMRR flags are set during intel_dp_compute_as_sdp.
--v4:
- Use drm_mode_vrefresh instead of manual calculation (Ankit).
