[PATCH v2 1/2] dt-bindings: mfd: mediatek: mt6397: add adc, codec and regulators for mt6359

[Macpaul Lin <macpaul.lin@mediatek.com>]

Since MT6359 PMIC has been added as one of the compatibles of
"mediatek,mt6397.yaml", the sub-device node of "MT6359 PMIC AUXADC",
"MT6359 Audio Codec"  and "MT6359 PMIC Regulators" should also be
contained in this DT Schema as well.

This patch includes:
 - add 'adc' property and $ref for 'mediatek,mt6359-auxadc'.
 - add 'mt6359-regulator' to the compatibles of regulators.
 - add 'mt6359-codec' to the compatibles of audio-codec.
