229e368239 USB: gadget: udc: 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.

0de9742514 usb: bdc: Add support for suspend/resume
Based on a previous commit by Danesh Petigara <dpetigara@broadcom.com>
that added resume to solve the following problem:
"The BDC driver will fail after resuming from S3 suspend and this
will cause any upper layer gadget driver to fail."
This commit also adds support for suspend and manages the clock during
suspend/resume.

5916733e9b usb: bdc: Fix misleading register names
The BDC endpoint status registers 0-7 were originally each going
to be an array of regsiters. This was later changed to being a
single register. The register definitions are being changed from:
"#define BDC_EPSTS0(n)  (0x60 + (n * 0x10))"
to
"#define BDC_EPSTS0	0x60"
to reflect this change and to avoid future coding mistakes.
