[media] saa7115: add config flag to change the IDQ polarity
Needed by the go7007 driver: it assumes a different polarity of the IDQ signal, so we need to be able to tell the saa7115 about this. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
