This patch adds support for the Analog Devices ADV7611 HDMI receiver.
The adv7611 is quite similar to the adv7604. It has only one instead of four
HDMI inputs and no analog frontend though. Also some register bits have been
shuffled around, but large parts of their register maps are compatible.

When suspending a device while a video stream is active all buffers
marked as done but not dequeued yet will be kept across suspend and
given back to userspace after resume. This will result in outdated
buffers being dequeued.
Introduce a new vb2 function to mark all done buffers as erroneous
instead, to be used by drivers at resume time.

When stopping a video stream the driver waits for ongoing DMA opeations
to complete for the currently active buffer, but doesn't release the
non-active queued buffers. This isn't a problem in most cases as the
video device is usually closed after the stream is stopped, which will
release all the buffers. However the problem would generate a warning
when switching to videobuf2. Fix it by cancelling all buffers after DMA
operations have completed.
