drm/i915/dp: Compute as_sdp.vtotal based on vrr timings

Browse Source 
Compute as_sdp.vtotal based on minimum vtotal calculated
during vrr computation.

--v2:
 - make a separate patch and update to vmin only [Ankit].

--v3:
 - Update vtotal to vmin for cmrr case as well [Ankit].

--v4:
 - update vtotal with wrapper function of vmin [Ville]
