From: Li Zhang <zhlcindy@xxxxxxxxxxxxxxxxxx>
PPC64 prefers to set pci-ohci controller as default USB controller.
Currently, libvirt is using legacy USB controller as default. There
are problems with VGA which can't work correctly with USB Keyboard and
USB Mouse.
This patch is to set pci-ohci as USB default controller.
