cx18: allow for simultaneous digital and analog capture
From: Hans Verkuil <hverkuil@xs4all.nl> The HVR-1600 can do both analog and digital capture at the same time. Due to a driver bug -EBUSY would be returned when attempting to setup an analog capture while a digital capture was already in progress. Separate the two internally. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
