Subject: [PATCH 2/6] ASoC: dt-bindings: midas-audio: Add separate
 compatible for tab3 audio

Unlike the Midas, the Galaxy Tab 3 8.0 does not have a main/sub mic
bias regulator, but it does have a separate headset mic bias regulator.

Add a new compatible for the Tab 3's audio and declare required
regulators separately based on the provided compatible.
