    [UNTESTED] use correct GPIO for hybrid driver on lenovo/T400
    
    Currently the hybrid driver uses GPIO 52 to configure mux. This is not
    the right GPIO on t400 according to schematics "MALIBU-3". 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.
