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.

This gets rid of the deprecated do_gettimeofday() function in usbip.
The comment above vgadget_get_frame() mentions that it suffers
from issues with the time jumps due to suspend and settimeofday,
so I'm changing it to use ktime_get_ts64() to use monotonic times
that don't have this problem.
I couldn't tell whether we should use CLOCK_MONOTONIC or
CLOCK_MONOTONIC_RAW here, the difference being the exact rate
when correcting for NTP. I picked monotonic time since it doesn't
change the speed to the existing code and should be better
synchronized with other machines we talk to.

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.

The only caller of get_gadget_descs() has already dereferenced udc
before calling this function, so udc can not be NULL at this point of
the code and hence no use of checking it.

One line above we have checked that udc is NULL so we shouldn't
dereference it while printing error message.

We read a struct usb_device_descriptor from it, so make it an actual
binary attribute.

Add sysfs attributes to allow controlling vudc from usbip tools.
dev_desc - device descriptor of current gadget. This is required to
be consisten with current usbip protocol and allow to list
exportable devices on given machine.
usbip_sockfd - allows to pass socket to kernel to start usbip transfer.
usbip_status - currnent status of device
