HID: wacom: Use half of brightness for low state
Intuos4 WL leds have 2 states: high and low. With no activity tablet uses low state; using pen triggers high state. Both can be set independently, but it would require setting another led device to control them separately. This patch uses the brightness set through leds subsytem as high and half of that value as low.
