[PATCH 3/6] DM USB: introduce struct usb_native_devinfo


Wu, Xiaoguang
 

Current design cannot get physical USB device information without
the creation of pci_xhci_dev_emu. This brings some dificulties in
certain situations, hence struct usb_native_devinfo is introduced
to describe neccessary information to solve this trouble.
