drm/i915/vrr: Enable CMRR

Browse Source 
Set crtc_state->vrr.cmrr.enable at the end of
intel_vrr_cmrr_compute_config() so that CMRR is actually enabled once
the M/N parameters have been computed. This is the final step that
turns on CMRR, with all the parameter computation handled in the
earlier patches.

--v2:
- Everything else except enable compute to handle before this patch
(Chaitanya)

--v3:
- Remove redundant return from compute config

--v4:
- Update CMRR commit message (Chaitanya)
