USB: musb: Use the correct style for SPDX License Identifier This patch corrects the SPDX License Identifier style in header files related to USB Dual Role (OTG-ready) Controller Drivers. 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: musb: Remove redundant license text Now that the SPDX tag is in all USB files, that identifies the license in a specific and legally-defined manner. So the extra GPL text wording can be removed as it is no longer needed at all. This is done on a quest to remove the 700+ different ways that files in the kernel describe the GPL license text. And there's unneeded stuff like the address (sometimes incorrect) for the FSF which is never needed. No copyright headers or other non-license-description text was removed.

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.

Also add the SW babble control register definitions. Babble control register logic is implemented in the latest revision of AM335x. Find whether we are running on newer silicon. The babble control register reads 0x4 by default in newer silicon as opposed to 0 in old versions of AM335x. Based on this enable the sw babble control logic.

Currently the default register access mode is set to FLAT_MODE thus INDEX register is not getting set properly with musb_ep_select() which is just a nop operation in FLAT_MODE.This invalid register read is causing module reinset failure.
