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

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.
