ASoC: dt-bindings: Convert TI TWL4030 sound

Merge series from Jihed Chaibi <jihed.chaibi.dev@gmail.com>:

This series converts the legacy TXT bindings for the TI TWL4030
sound-related modules to the modern YAML DT schema format.

This work was previously part of a larger series but is now being sent
as a focused submission for the ASoC subsystem.
