pci-ohci might habe been disabled in the QEMU binary (e.g. when "configure"
has been run with "--without-default-devices"). Thus we should check
for its availability before blindly using it.

Considering that PowerMacs have an OHCI controller built in soldered to the motherboard should this depend on it instead and not rely on pulling it in with PCI_DEVICES and --without-default-devices disabling it?

Currently it's not quite emulating a real Mac but I think we should aim for going that way rather than to keep emulating random Mac hardware.


    has_pmu = (core99_machine->via_config != CORE99_VIA_CONFIG_CUDA);
    has_adb = (core99_machine->via_config == CORE99_VIA_CONFIG_CUDA ||
               core99_machine->via_config == CORE99_VIA_CONFIG_PMU_ADB);
