Supports SSP scheduling only for SSP device directly connected
to root hub but not through external USB3 gen2 hub which need
use a new scheduling way.

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.

There some vendor quirks for MTK xhci host controller:
1. It defines some extra SW scheduling parameters for HW
to minimize the scheduling effort for synchronous and
interrupt endpoints. The parameters are put into reseved
DWs of slot context and endpoint context.
2. Its IMODI unit for Interrupter Moderation register is
8 times as much as that defined in xHCI spec.
3. Its TDS in Normal TRB defines a number of packets that
remains to be transferred for a TD after processing all
Max packets in all previous TRBs.
