usb core: use qdev for -usbdevice
This patchs adds infrastructure to handle -usbdevice via qdev callbacks.
USBDeviceInfo gets a name field (for the -usbdevice driver name) and a
callback for -usbdevice parameter parsing.
The new usbdevice_create() function walks the qdev driver list and looks
for a usb driver with a matching name. When a parameter parsing
callback is present it is called, otherwise the device is created via
usb_create_simple().
