[media] vivid: add support for radio receivers and transmitters
This adds radio receiver and transmitter support. Part of that is common
to both and so is placed in the radio-common source.
These drivers also support RDS. In order to generate valid RDS data a
simple RDS generator is implemented in rds-gen.
