The emulated OHCI controller in QEMU has some bugs and performance issues, so for pseries machine, it's desirable to switch to the XHCI device instead. To keep the old pseries machine versions compatible, this patch series also introduces a flag in the SPAPR machine class that can be used to signal that the OHCI controller should be still instantiated instead when the default settings are used.
Note: The patches should be applied after my 'Remove duplicated "pseries" alias' patch that I've sent a couple of days ago (it's currently not in master yet, just in David's ppc-for-2.5 branch).
