Adaptive sync sdp param computation, specifically minimum vtotal is
blocking vrr enable and disable fastset requirements in certain scenario
i.e. during null modeset, this minimum vtotal we can configure during
full modeset as well when sink is having vrr support, where it doesn't
need dependency on vrr.enable status and can also match vrr
enable/disable fastset requirement.
