V4L/DVB (3317): msp3400: use v4l2_std_id and determine chip capabilities.
- Replace old norm by the v4l2_std_id values. - Add code to correctly detect the various capabilities of the various msp chips. It's not yet used, that's going to be the next step. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@brturbo.com.br>
