All these files have been updated in the commit given in the Fixes: tag
below.
When the SPDX-License-Identifier: has been added, the corresponding text at
the beginning of the files has not been deleted.
All these texts are about GPL-2.0+, with different variation in the
wording.
Remove these now useless lines to save some LoC.
Fixes: 5fd54ace47
("USB: add SPDX identifiers to all remaining files in drivers/usb/")
