The last step the usb_driver (*probe) does before handing off to the
comedi_driver (*auto_attach) is requesting and uploading the firmware.

Move the request/upload into the (*auto_attach) so we can use the

Absorb the usbduxsub_stop(), usbduxsub_upload(), and usbduxsub_start()
functions into firmwareUpload().

Each of them just do a usb_control_msg() to the device and output
an error message if it fails. A similar message is also output by
firmware_upload() so the extra messages are redundant.

We can also share the malloc'ed local buffer needed for the
usb_control_msg().

This driver uses the comedi auto attach mechanism so the comedi_device
will always have an associated usb_interface and usb_device.

attached. This also allows removing the usb_interface from the private
