ASoC: add support for TAS5805M digital amplifier

This pair of patches implements support for the TAS5805M class D audio amplifier. This driver, and the example configuration in the device-tree file, were originally based on a 4.19 series kernel and have been modified very slightly from the tested version (digital_mute has been replaced with mute_stream, and the new IS_ENABLED macro is used).
