Time period for HDCP2.2 link check.

Not sure if we need a separate patch for this. Could be merged where check_link is introduced for hdcp2.2.
If there is a valid reasoning, no hard objection and it looks ok in general. So
drm level change is convenient to have in separate patch to get approval from dri-devel.
