usb: musb: add tracepoints for register access This adds tracepoints to musb register read/write wrappers to get trace log for register access. The default tacepoint log prefix here would be musb_readX/writeX(), which is not much helpful. So this patch let the tracepoints use __buildin_return_address(0) to print the caller funciton name to provide more context of the register access.
