[media] si4713: add the missing RDS functionality
Not all the RDS features of the si4713 were supported. Add the missing bits to fully support the hardware capabilities. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Cc: Eduardo Valentin <edubezval@gmail.com> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
