[PATCH] usb: raw-gadget: upgrade license identifier

[andrey.konovalov@linux.dev]

From: Andrey Konovalov <andreyknvl@gmail.com>

Most of the USB gadget modules are licensed as GPL-2.0+. There is no
reason not to allow using Raw Gadget code under a newer GPL version.

Change SPDX identifier from GPL-2.0 to GPL-2.0+.

I don't know whether such license change is possible and what it
requires.

Initially, when creating raw_gadget.c, I just copied GPL-2.0 from
somewhere as it didn't seem to matter. Recently, I was looking into
adding a license to a project that reuses both dummy_hcd.c and
raw_gadget.c, and I noticed the difference in licensing rules.

Hence this patch.
