Compute and check if dsc and scaler prefill latency is sufficient with
respect to vblank.

Previous Revision Reference:
https://patchwork.freedesktop.org/series/141203/

Mitul Golani (7):
  drm/i915/scaler: Add and compute scaling factors
  drm/i915/scaler: Use crtc_state to setup plane or pipe scaler
  drm/i915/scaler: Refactor max_scale computation
  drm/i915/scaler: Compute scaling factors for pipe scaler
  drm/i915/scaler: Limit pipe scaler downscaling factors for YUV420
  drm/i915/scaler: Check if vblank is sufficient for scaler
  drm/i915/dsc: Check if vblank is sufficient for dsc prefill
