From: Animesh Manna <animesh.ma...@intel.com>

As vrr guardband calculation is dependent on modified
vblank start so better to compute late after all
vblank adjustement.

v1: Initial version.
v2: Split in a separate patch from panel-replay workaround. [Ankit]
v3: Add a function for late vrr related computation. [Ville]
v4: Use flipline instead of vrr.enable and some cosmetic changes. [Ville]
v5: Use intel_vrr_possible helper.
