Subject: Enhance liblights to support touchkey backlight

Adds the necessary function to control capacitive key backlight from userspace

Set BOARD_BUTTON_LIGHTS_PATH in BoardConfig to the relevant device node path to enable this

Used by Infuse4g at least - May be applicable to other devices? (epicmtd has a similar function in their liblights)
