DM USB: xHCI: refine the de-init logic of xHCI vdevice

Browse Source 
Add 'full' and 'non-full' de-initialize support for xHCI virtual
device. The non-full de-initialization mainly release usb_dev
structure and unbind the usbfs with native device. And the full
de-initialize will release all the resources allocated for xHCI
virtual device including the unbinding operation mentioned above
