Subject: [PATCH v2 1/2] dt-bindings: mfd: mt6397: Add compatibles for MT6331 RTC and keys

The MT6331 PMIC provides many sub modules: regulators, audio
codec, LED controller, keys, RTC and some GPIOs.
It is always paired with a MT6332 Companion PMIC, which provides
thermistors, WLEDs (display LED backlight), secondary AP cluster
regulators, modem clocks, battery charger and fuel gauge.

Add the necessary compatibles to start implementing the basics.
