When the battery is dry and BATTERY_FULL_DISCHARGED is set,
we should check BATTERY_DISCHARGING to decide the power status.
If BATTERY_DISCHARGING is set, the power status is not charging.
Or the power status should be charging.

Document the device-tree binding of MediatTek display PWM.
The PWM has one channel to control the backlight brightness for display.
It supports MT8173 and MT6595.

Add display PWM driver support to modify backlight for MT8173 and MT6595.
The PWM has one channel to control the brightness of the display.
When the (high_width / period) is closer to 1, the screen is brighter;
otherwise, it is darker.

clocks of MT8173
Change in v6:
1. Enable clocks in the pwm_enable function
2. Remove suspend/resume code since pwm-backlight driver has done the same
things
3. Revise some code to make it easier to read
