Origianl description for v1 patch 

	drm/bridge: it6505: fix hibernate to resume no display issue

	ITE added a FIFO reset bit for input video. When system power resume,
	the TTL input of it6505 may get some noise before video signal stable
	and the hardware function reset is required.
	But the input FIFO reset will also trigger error interrupts of output module rising.
	Thus, it6505 have to wait a period can clear those expected error interrupts
	caused by manual hardware reset in one interrupt handler calling to avoid interrupt looping.
