From: ChiYuan Huang <[email protected]>
This adds support for the MediaTek MT6370 SubPMIC. 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.

v5
- Add the comma in the last REGMAP_IRQ_REG_LINE(),
DEFINE_RES_IRQ_NAMED() and MFD_CELL_RES()
- Add the prefix in the first parameter of all mfd_cell
- Move enum and struct mt6370_info to mt6370.h
- Remove struct device *dev in struct mt6370_info
- Revise the description of Kconfig help text
- Revise MODULE_DESCRIPTION()
