V4L/DVB (13644): v4l: add new v4l2-subdev sensor operations, use g_skip_top_lines in soc-camera
Introduce new v4l2-subdev sensor operations, move .enum_framesizes() and .enum_frameintervals() methods to it, add a new .g_skip_top_lines() method and switch soc-camera to use it instead of .y_skip_top soc_camera_device member, which can now be removed.
