Subject: [PATCH v2] USB: add SPDX identifiers to all remaining files in
 drivers/usb/

It's good to have SPDX identifiers in all files to make it easier to
audit the kernel tree for correct licenses.

Update the drivers/usb/ and include/linux/usb* files with the correct
SPDX license identifier based on the license text in the file itself.
The SPDX identifier is a legally binding shorthand, which can be used
instead of the full boiler plate text.

This work is based on a script and data from Thomas Gleixner, Philippe
Ombredanne, and Kate Stewart.

v2: Use the "standard" format of putting the identifier at the top of
    the file, and use // for .c and .h files.
    Removed the files already marked in Linus's tree.

Unless someone really complains, I'm going to add this to my tree for
4.15-rc1.
