qdev/usb: add usb bus support to qdev, convert drivers.
* Add USBBus. * Add USBDeviceInfo, move device callbacks here. * Add usb-qdev helper functions. * Switch drivers to qdev. TODO: * make the rest of qemu aware of usb busses and kill the FIXMEs added by this patch. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
