The TI TAS5722 digital amplifier is very similar to the TAS5720 from an overall and register map perspective. Therefore the existing driver can be extended easily to support this additional device. This commit allows TAS5722 devices to be used in a "subset" type of fashion, without exposing any of the additional features they offer.
