[media] adv7604: add support for all the digital input ports
The adv7604 supports four digital input ports. This patch adds support for all of them, instead of just port A. Signed-off-by: Mats Randgaard <matrandg@cisco.com> Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
