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 Armada 375/38x XHCI controllers The Armada 375 and 38x SoCs come with an XHCI controller that requires some specific initialization related to the MBus windows configuration. This patch adds the support for this special configuration as an XHCI quirk executed during probe. Two new compatible strings are added to identify the Armada 375 and Armada 38x XHCI controllers, and therefore enable the relevant quirk.

usb: host: xhci: mvebu: add reset on resume quirk The mvebu xHCI host driver does not have suspend/resume support. Use of the XHCI_RESET_ON_RESUME quirk is mandatory in order to avoid failures after resume. This will work only if no USB device is plugged-in. While at it, mention in the Kconfig file that this IP is also present on the A3700 SoC.
