media: uvcvideo: Implement dual stream quirk to fix loss of usb packets

[ Upstream commit c2eda35e675b6ea4a0a21a4b1167b121571a9036 ]

Some cameras, such as the Sonix Technology Co. 292A, exhibit issues when
running two parallel streams, causing USB packets to be dropped when an
H.264 stream posts a keyframe while an MJPEG stream is running
simultaneously. This occasionally causes the driver to erroneously
output two consecutive JPEG images as a single frame.

To fix this, we inspect the buffer, and trigger a new frame when we
find an SOI.
