power: supply: mt6370: Add MediaTek MT6370 charger driver

Browse Source 
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.

Say Y here to enable MT6370 Charger Part.
The device supports High-Accuracy Voltage/Current Regulation,
Average Input Current Regulation, Battery Temperature Sensing,
Over-Temperature Protection, DPDM Detection for BC1.2.
This driver can also be built as a module. If so, the module
will be called "mt6370-charger".
