Actually one of the opens I had here was regarding the min and max calculation
in intel_pipe_update_start aroudn teh vblank evasion code.
Currently we have:
min = vblank_start - intel_usecs_to_scanlines(adjusted_mode,
VBLANK_EVASION_TIME_US);

VRR achieves vblank stretching using the HW PUSH functionality.
So once the VRR is enabled during modeset then for each flip
request from userspace, in the atomic tail pipe_update_end()
we need to set the VRR push bit in HW for it to terminate
the vblank at configured flipline or anytime after flip
