usb: gadget: add tracepoints to the gadget API
This new set of tracepoints will help all gadget drivers and UDC drivers when problem appears. Note that, in order to be able to add tracepoints to udc-core.c we had to rename that to core.c and statically link it with trace.c to form udc-core.o. This is to make sure that module name stays the same. Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com>
