[PATCH v6 07/22] usb: dwc2: host: Add scheduler tracing

In preparation for future changes to the scheduler let's add some tracing that makes it easy for us to see what's happening. By default this tracing will be off. By changing "core.h" you can easily trace to ftrace, the console, or nowhere. Signed-off-by: Douglas Anderson Reviewed-by: Kever
