af9c7c11e9 sandbox: usb: Allow finding a USB emulator for a device 
Each USB device has an emulator. Currently this can only be found by
supplying the 'pipe' value, which contains the device number. Add a way
to find it directly from the emulated device.

019808f97c dm: usb: sandbox: Add a uclass for USB device emulation 
With sandbox we want to be able to emulate USB devices so that we can test
the USB stack. Add a uclass to support this. It implements the same
operations as a normal USB device driver, but in this case passes them on
to an emulation driver.
