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: host: xhci-plat: add support for the R-Car H2 and M2 xHCI controllers The R-Car H2 and M2 SoCs come with an xHCI controller that requires some specific initializations related to the firmware downloading and some specific registers. This patch adds the support for this special configuration as an xHCI quirk executed during probe and start.

usb: host: xhci-plat: add support for the R-Car H3 xHCI controllers The R-Car H3 has two xHCI controllers. This SoC is compatible with R-Car Gen2 SoCs, however this SoC doesn't need some specific registers setting, and need a new firmware.
