Machine types cubieboard, xlnx-ep108, xlnx-zcu102 have an onboard AHCI
controller, but neglect to set their MachineClass member
units_per_default_bus = 1. This permits -drive if=ide,unit=1, which
makes no sense for AHCI. It also screws up index=N for odd N, because
it gets desugared to unit=1,bus=N/2
Doesn't really matter, because these machine types fail to honor
-drive if=ide. Add the missing units_per_default_bus = 1 anyway,
along with a TODO comment on what needs to be done for -drive if=ide.
Also set block_default_type = IF_IDE explicitly. It's currently the
default, but the next commit will change it to something more
sensible, and we want to keep the IF_IDE default for these three
machines. See also the previous commit.
