drivers: video: add line_offset field to video_buffer structure

Browse source 
Add line_offset field to the video_buffer structure. This field
indicates the offset (in horizontal lines) within a frame that a video
buffer starts at. This is useful for video devices that produce or
consume video buffers that constitute a partial frame.
