V4L/DVB (8113): ivtv/cx18: remove s/g_ctrl, now all controls are handled through s/g_ext_ctrl
videodev converts old-style controls to an extended control so the ivtv and cx18 drivers no longer have to handle both. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
