Subject: [PATCH v2 RESEND 08/14] soundwire: mipi-disco: remove DPn audio-modes

From: Pierre-Louis Bossart <pierre-louis.bossart@...ux.intel.com>

The concept of DPn audio-modes was never used by anyone, and was
removed from the DisCo for SoundWire 2.0 specification.

Remove the definitions and TODO.
