That is the default name. For usb controllers added via -device the bus
name is derived from the device name, i.e. '-device usb-ehci,id=ehci"
gives you a bus named "ehci.0".
For builtin devices that doesn't work though as you don't have to add
them manually. Guess they should be explicitly named then by zynq_init().
cheers,
