In order to allow external SoC-dependent glue drivers to use dwc3-generic functions, push the glue structures and export the functions to a header file.
The exported structures and functions are:
- struct dwc3_glue_data - struct dwc3_glue_ops - dwc3_glue_bind() - dwc3_glue_probe() - dwc3_glue_remove()
The SoC-dependent glue drivers can only define their own wrapper driver and specify these functions. The drivers can also add their own compatible strings and configure functions.
