"GBF" - Keypad Brightness auto follow
This command controls if the keypad brightness level will follow the LCD backlight brightness, follow the brightness
sensor, or if the keypad brightness shall be manually set by BRL command. If the GBF command is set to follow the
LCD backlight brightness, or the light sensor brightness, the result is scaled by the BRL.
