As per spec, the CAPTURE resolution should be automatically set based on the OTUPUT resolution. This patch properly propagate width/height to the capture when the OUTPUT format is set and override the user provided width/height with configured OUTPUT resolution when the CAPTURE fmt is updated.
This also prevents userspace from selecting a CAPTURE resolution that is too small, avoiding unwanted page faults.
