[libvirt] [PATCH 1/6] extend usb controller model to support xen pvusb

[Chunyan Liu]

According to libxl implementation, it supports pvusb
controller of version 1.1 and version 2.0, and it
supports two types of backend, 'pvusb' (dom0 backend)
and 'qusb' (qemu backend).

To match libxl support, extend usb controller schema
to support more models: pvusb1 (pvusb, version 1.1),
pvusb2 (pvusb, version 2.0), qusb1 (qusb, version 1.1)
and 'qusb2' (qusb version 2.0).
