lenovo/x60: Enable brightness controls (native graphics)

This makes the Fn Home/End keys work for controlling the
    brightness of the display. Value obtained by reading
    BLC_PWM_CTL when running the VBIOS (option ROM).

On i945 legacy brightness control is enabled by a single
    bit in BLC_PWM_CTL. It's bit 16 or bit 0 (the other one
    reverses polarity). Set the bit to enable brightness
    controls.
