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.

%p will leak kernel pointers, so let's not expose the information on
dmesg and instead use %pK. %pK will only show the actual addresses if
explicitly enabled under /proc/sys/kernel/kptr_restrict.

One big merge this time with a total of 166 non-merge commits.
Most of the work, by far, is on dwc2 this time (68.2%) with dwc3 a far
second (22.5%). The remaining 9.3% are scattered on gadget drivers.
The most important changes for dwc2 are the peripheral side DMA support
implemented by Synopsys folks and support for the new IOT dwc2
compatible core from Synopsys.
In dwc3 land we have support for high-bandwidth, high-speed isochronous
endpoints and some non-critical fixes for large scatter lists.
Apart from these, we have our usual set of cleanups, non-critical fixes,
etc.

Pull MFD fixes from Lee Jones:
"Contained are some standard fixes and unusually an extension to the
Reset API. Some of those changes are required to fix a bug introduced
in -rc1, which introduces extra 'reset line checks' i.e. whether the
line is shared or not. If a line is shared and the new *_shared() API
is not used, the request fails with an error. This breaks USB in v4.7
for ST's platforms.
Admittedly, there are some patches contained in our (MFD/Reset)
immutable branch which are not true -fixes, but there isn't anything I
can do about that. Rest assured though, there aren't any API
'changes'. Everything is the same from the consumer's perspective.

Set USB3_FORCE_VBUSVALID when configured for USB_DR_MODE_PERIPHERAL
mode, as it is required to have a working setup.
This worked on the internal driver by relying on the reset
value of the syscfg register as the bits aren't explicity cleared
and set like the upstream driver.
Also add a comment about what setting this bit means.
