When the system power resumes, the TTL input of IT6505 may experience
some noise before the video signal stabilizes, necessitating a video
reset. This patch is implemented to prevent a loop of video error
interrupts, which can occur when a video reset in the video FIFO error

From: Kuro Chung
This patch 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
