dm: usb: Clean up USB after each test
The USB subsystem has a few counters that need to be reset since they are stored in static variables rather than driver-model data. An example is usb_max_devs. Ultimately we should move this data into the USB uclass. For now, make sure that USB is reset after each test, so that the counters go back to zero. Note: this is not a perfect solution: It a USB test fails it will exit immediately and leave USB un-reset. The impact here is that it may cause subsequence test failures in the same run.
