Now that the SPDX tag is in all USB files, that identifies the license
in a specific and legally-defined manner. So the extra GPL text wording
can be removed as it is no longer needed at all.
This is done on a quest to remove the 700+ different ways that files in
the kernel describe the GPL license text. And there's unneeded stuff
like the address (sometimes incorrect) for the FSF which is never
needed.
No copyright headers or other non-license-description text was removed.

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.

If PHY is suspended by the time we want to issue ULPI transfers, we
will observe timeouts on the ULPI interface. In order to avoid such
issue, let's make sure PHY is resumed before issuing a ULPI transfer.

ulpi_register_interface() accepts a const struct ulpi_ops and dwc3
doesn't perform any changes to this struct at runtime, so there's no
reason it shouldn't be constant.

With the removal of the old {read|write} operations, we can now safely
rename the new api operations {read|write}_dev to use the shorter and
clearer names {read|write}, respectively.

The old read, write callbacks in struct ulpi_ops have been deprecated
in favor of new callbacks that pass the parent device directly.
Replace the used callbacks in dwc3's ulpi component with the new api.
