usb: New usb_new(), usb_realize_and_unref()

I'm converting from qdev_create()/qdev_init_nofail() to
qdev_new()/qdev_realize_and_unref(); recent commit "qdev: New
qdev_new(), qdev_realize(), etc." explains why.

USB devices use qdev_create() through usb_create().

Provide usb_new() and usb_realize_and_unref() for converting USB
devices.
