[PATCH] USB: wireless usb <linux/usb_ch9.h> declarations

This provides declarations for new requests, descriptors, and bitfields as
defined in the Wireless USB 1.0 spec.  Device support will involve a new
"Wire Adapter" device class, connecting a USB Host to a cluster of wireless
USB devices.  There will be two adapter types:

  * Host Wireless Adapter (HWA):  the downstream link is wireless, which
    connects a wireless USB host to wireless USB devices (not unlike like
    a hub) including to the second type of adapter.

  * Device Wireless Adapter (DWA): the upstream link is wireless, for
    connecting existing USB devices through wired links into the cluser.

All wireless USB devices will need persistent (and secure!) key storage, and
it's probable that Linux -- or device firmware -- will need to be involved
with that to bootstrap the initial secure key exchange.

Some user interface is required in that initial key exchange, and since the
most "hands-off" one is a wired USB link, I suspect wireless operation will
usually not be the only mode for wireless USB devices.  (Plus, devices can
recharge batteries using wired USB...)  All other key exchange protocols need
error prone user interactions, like copying and/or verifying keys.

It'll likely be a while before we have commercial Wireless USB hardware,
much less Linux implementations that know how to use it.
