usb: dwc3: Log dwc3 address in traces

When multiple DWC3 controllers are being used, trace events from
different instances get mixed up making debugging difficult as
there's no way to distinguish which instance generated the trace.

Use the register base address of dwc3 controller and append it to
trace events, so that the source instance is clearly identifiable.

Example trace output,
before ->  dwc3_event: event (00000101): Reset [U0]
after  ->  dwc3_event: 0x000000000a600000: event (00000101): Reset [U0]
