leds: rgb: mt6370: Add MediaTek MT6370 current sink type LED Indicator support 



The MediaTek MT6370 is a highly-integrated smart power management IC,
which includes a single cell Li-Ion/Li-Polymer switching battery
charger, a USB Type-C & Power Delivery (PD) controller, dual
Flash LED current sources, a RGB LED driver, a backlight WLED driver,
a display bias driver and a general LDO for portable devices.

Add support for the MediaTek MT6370 Current Sink Type LED Indicator
driver. It can control four channels current-sink RGB LEDs with 3 modes:
constant current, PWM, and breath mode.

	  In MT6370, there are four channel current-sink LED drivers that

	  Isink4 channel can also be used as a CHG_VIN power good indicator.
