This regulator is not used on the board. Shall I set the name to 'NC'
or is there a way to completely disable this one?

The codec is not used yet in the dtb. As I saw on an other board
(imx8mn-var-som.dtsi) there was also just a placeholder. I can also
add an comment here.

About the order I did not checked correctly. I can bring this in the
right order for sure. But about the needs I hope someone from e.g.
from NXP can give a hint.
