1fab219e65 usb: mtu3: clear SOFTCONN when clear USB3_EN if work as HS mode
When the controller supports SS mode, but works as HS mode, the
SOFTCONN will not be cleared automatically when clear USB3_EN
by default, this cause an issue that can't disconnect from host,
so clear SOFTCONN when clear USB3_EN when the class driver want
to disable the D+ pullup.

94552090cd usb: mtu3: enable SETUPENDISR interrupt
If the controller receives a new SETUP during SETUP data stage,
and will generate SETUPENDISR interrupt, the driver should abort
the current SETUP command and process the new one.

78af87b8bb usb: mtu3: fix error of xhci port id when enable U3 dual role
If dual role mode is enabled, when switch u3port0 to device mode,
it will affect port id calculation of host(xHCI), specially when
host supports multi U2 ports or U3 ports, so need enable its dual
role mode, and fix it here.

4c55a15774 USB: mtu3: Remove redundant license text
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.

5fd54ace47 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.
