ASoC: dt-bindings: clarify areg-supply documentation 

The documentation for areg-supply could cause confusion mainly in terms
of the relationship between AREG and AVDD.
According to the datasheet[1] the AREG can be one of two cases:

1) an external 1.8V supply
2) generated by an internal regulator (hence a 1.8V output)
