Our current MPEG-2 uAPI uses 1-byte fields for MPEG-2
boolean syntax elements. Clean these by adding a 'flags'
field and flag macro for each boolean syntax element.
Move quantization "load" flags to struct v4l2_mpeg2_picture,
so the applications can skip passing the quantization matrices
(by not setting the MPEG2_QUANTIZATION control in decode request).
A follow-up change will refactor this uAPI so we don't need
to add padding fields just yet.
