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.

usb: gadget: uvc: Minimize #include in headers In order to speed up compilation, only include the headers that are strictly required within other headers. To that end, use forward structure declaration and move #include statements to .c file as appropriate. While at it, sort headers alphabetically, and remove unneeded __KERNEL__ guards.

usb: gadget: uvc: Replace plain printk() with dev_*() Adding device context to the kernel log messages make them more useful. Add new uvcg_* macros based on dev_*() that print both the gadget device name and the function name. While at it, remove a commented out printk statement and an unused printk-based macro.
