ASoC: dt-bindings: ti,pcm1681: Document the PCM1681 supplies
The PCM1681 takes a 5V analog supply on VCC1 and VCC2 and a 3.3V
digital supply on VDD. On boards where these rails are switchable, the
codec has to know about them to be able to power the DAC up and down,
which needs a way to describe the connections in Device Tree.
Document the VCC1, VCC2 and VDD supply properties.
