Manage button and keyboard backlights with light sensor in both manual and automatic mode.

Browse Source 
Now the manual brightness mode only applies to the LCD backlight and
button and keyboard backlights are always managed automatically.

Fixes bug b/2195798 (Passion capacitive key backlights don't always come on)

This change only affects the framework based auto-brightness implementation.
Hardware auto-brightness is not affected.
