    [UNTESTED] lenovo/T400: correct GPIO for hybrid driver
    
    Currently the hybrid driver uses GPIO 52 to configure mux. This is not
    the right GPIO on the T400 according to the schematics "MALIBU-3 EXT".
    It should be GPIO22.
    
    Previously also gpio 49 (GFX_PWR_EN), 19 (BKLT_CTRL_SEL),
    17 (DGFX_PWRGD) were configured for hybrid graphics to
    work on T400, but this was reverted in 14d1a93e: "Revert
    mainboard/lenovo/t400: Add initial hybrid graphics support". It is
    unknown if this is also needed.
