As some faulty displays generate long HPDs even while connected to ports
can cause CI execution issues. Add a provision to ignore such long HPDs
in such systems with control through debugfs

Vinod Govindapillai (2):
  drm/i915/display: ignore long HPDs based on a flag
  drm/i915/display: debugfs entry to control ignore long hpd flag
