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.

In MediaTek MT6370, there are four channel current-sink RGB LEDs that
support hardware pattern for constant current, PWM, and breath mode.
Isink4 channel can also be used as a CHG_VIN power good indicator.

v6
- Remove the 'ko' from mt6370 led Kconfig description.
- Add both authors for Alice and ChiYuan.
- Use pdata to distinguish the code from mt6370/71 to mt6372.
- Instead of 'state' define, use the 'state' enum.
- Fix the typo for 'MT6372_PMW_DUTY'.
- For pwm_duty define, replace with bit macro - 1.
- Refine all the labels from 'out' to 'out_unlock'.
- Use struct 'dev' variable and 'dev_err_probe' to optimize the LOC.
- Revise for the array initialization from {0} to {}.
- Move into rgb folder and rename file name to 'leds-mt6370-rgb'.
- Refine the 'comma' usage in struct/enum.
