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.

Change in v5:
1. Configure PWM output via pinctrl.
2. Fix the parameter name in dtsi.

Change in v4:
1. Codebase is on v4.2-rc1.
2. Add the PWM node in dtsi.
3. Change the dependency in Kconfig.
4. Rewrite some code for readability.

Change in v3:
1. Add suspend/resume function.
2. Fix the formula for high_width calculation.
3. Rewrite some code to make it easier to read.
4. Add more information in the commit message.

Change in v2:
1. Rewrite descriptions for driver in kconfig to make it much clear.
2. Rename the driver from "pwm-mediatek-disp" to "pwm-mtk-disp".
3. Disable clocks in the error path.
4. Change the shift values in decimal instead of hex.
5. Rename and add some variables or function name for consistency and
readability.
6. Drop unnecessary parentheses, spaces, variables and add newlines to
make the code easiler to read.

Thanks for your suggestion.

Regards,
YH Huang
