power: supply: mt6370: Add MediaTek MT6370 charger driver
MediaTek MT6370 is a SubPMIC consisting of a single cell battery charger with ADC monitoring, RGB LEDs, dual channel flashlight, WLED backlight driver, display bias voltage supply, one general purpose LDO, and the USB Type-C & PD controller complies with the latest USB Type-C and PD standards. Add support for the MediaTek MT6370 Charger driver. The charger module of MT6370 supports High-Accuracy Voltage/Current Regulation, Average Input Current Regulation, Battery Temperature Sensing, Over-Temperature Protection, DPDM Detection for BC1.2.
