USB: mtu3: Use the correct style for SPDX License Identifier This patch corrects the SPDX License Identifier style in header files related to MediaTek USB3 Dual Role controller. For C header files Documentation/process/license-rules.rst mandates C-like comments (opposed to C source files where C++ style should be used). Changes made by using a script provided by Joe Perches here: https://lkml.org/lkml/2019/2/7/46.

usb: mtu3: add debugfs interface files This adds more debugfs consumers. The debugfs entries read some important registers, fifo status, QMU ring, endpoint status, and IPPC probe interface to get internal status. With these entries, users can check the registers, endpoint and GPD used during run time.
