So these drivers, all but one, are for PPC Macs (which we dropped any vestige
of when we dropped big endian. The only thing that isn't PPC specific is
CONFIG_MAC_EMUMOUSEBTN which we enable in Fedora but frankly I bet that is
already better dealt with by libinput so I think we can basically disable this
everywhere.
