V4L/DVB (11387): Sensor orientation reporting
Add support to the SQ-905 driver to pass back to user space the
sensor orientation information obtained from the camera during init.
Modifies gspca and the videodev2.h header to create the necessary
API.
[mchehab@redhat.com: Changed "Output is" to "Frames are" at the comments, as suggested at LMML]
