[patch 01/16] usb: introduce usb_device authorization bits

This just modifies 'struct usb_device' to contain the 'authorized'
bit. It also adds a 'wusb' bit. This is needed because nonauthorized
(and thus non-authenticated) wusb devices will fail certain kind of
simple requests (such as string descriptors). By knowing the device is
WUSB, we just avoid them.
