    peppy and falco: set panel power timings in northbridge, using devicetree, not mainboards
    
    Historically we had set panel timing in the mainboard gma code. This goes
    back to the replay-attack video startup.
    
    We can let the haswell gma code set these values from the device tree
    settings.
