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.

xhci: add traces for debug messages in xhci_address_device() This patch declares an event class for trace events that trace messages with variadic arguments, called xhci_log_msg, and defines a trace event for tracing the debug messages in xhci_address_device() function, called xhci_dbg_address. In order to implement this type of trace events, a wrapper function, called xhci_dbg_trace(), was created that records the format string and variadic arguments into a va_format structure which is passed as argument to the tracepoints of the class xhci_log_msg. All the xhci_dbg() calls in xhci_address_device() are replaced with calls to xhci_dbg_trace(). The functionality of xhci_dbg() log messages was not removed though, but it is placed inside xhci_dbg_trace(). This trace event aims to give the ability to the user or the developper to isolate and trace the debug messages generated when an Address Device Command is issued to xHC.
