    drivers/pc80: Add PS/2 mouse presence detect
    
    On certain Winbond SuperIO devices, when a PS/2 mouse is not
    present on the auxiliary channel both channels will cease to
    function if the auxiliary channel is probed while the primary
    channel is active.  Therefore, knowledge of mouse presence
    must be gathered by coreboot during early boot, and used to
    enable or disable the auxiliary PS/2 port before control is
    passed to the operating system.
    
    Add auxiliary channel PS/2 device presence detect, and update
    the Winbond W83667HG-A driver to flag the auxiliary channel as
    disabled if no device was detected.
