ASoC: add support for TAS5805M digital amplifier

The Texas Instruments TAS5805M is a class D audio amplifier with an
integrated DSP. DSP configuration is supplied in a firmware image
specified through a device-tree attribute.

These register writes set up application-specific DSP settings and are
expected to be generated using TI's PPC3 tool.
