The MediaTek mt6359 AUXADC also has a very similar binding. The mt6323
cannot be merged there because it has a different hardware.

Should this go as a child for the mt6397 mfd like mediatek,mt6323-led?
It currently references only mediatek,mt6359-auxadc.yaml, so perhaps
the mt6359 should be merged to the mfd, and then use oneOf for the
compatible property?
