The wusb code takes a very peculiar approach at implementing CBC-MAC,
by using plain CBC into a scratch buffer, and taking the output IV
as the MAC.
We can clean up this code substantially by switching to the cbcmac
shash, as exposed by the CCM template. To ensure that the module is
loaded on demand, add the cbcmac template name as a module alias.

There are a few remaining drivers/usb/ files that do not have SPDX
identifiers in them, all of these are either Kconfig or Makefiles. Add
the correct GPL-2.0 identifier to them to make scanning tools happy.

This patch removes the depends on USB from all config symbols in
drivers/usb/host/Kconfig and replace that with an if USB / endif block
as suggested by Alan Stern. Some source ... Kconfig lines have been
shuffled around to permit a better regroupment of the Kconfig files
depending on "config USB" item. No functionnal change is introduced.

As discussed at the kernel summit this year, CONFIG_EXPERIMENTAL means
nothing, so let's get rid of it.

The UWB stack has some sysfs APIs that will change thus it's best
marked as EXPERIMENTAL until these APIs are finalized.

Simplify the sysfs ABI of the wusb-cbaf (Cable Based Association)
driver: use one value per file and cause the write of the CHID to
fetch the CDID (instead of requiring a separate read).
Update the example wusb-cbaf script to work with this revised ABI.
