commit b47bcd779d8e0b2824f852c1b9d2a5c336622afc

    mainboard/lenovo/g505s: Build in EC ASL support for KBD/AUX ports
    
    Rather than have Linux report:
     i8042: PNP: No PS/2 controller found. Probing directly.
    and go off probing PNP config space, build in EC ASL for the
    PS/2 keyboard and mouse.
    
    The ASL explicitly passes these resources to the Linux to avoid
    said probe.
    
    ASL Details:
     PS/2 keyboard (PNP0303 at 0x60,0x64 irq 1 )
     PS/2 mouse    (PNP0F13 at 0x60,0x64 irq 12)
