staging: comedi: usbdux: use comedi_load_firmware()

Use comedi_load_firmware() instead of duplicating the code in a
private function.

Also, rename firmware_upload() to have namespace associated with
the driver.

staging: comedi: usbdux: move firmware request/upload into (*auto_attach)

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
comedi_load_firmware() helper.

staging: comedi: usbdux: consolidate the firmware upload

Absorb the usbdux_stop(), usbdux_upload(), and usbdux_start()
functions into firmware_upload().

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.

Converting this driver to use the comedi (*auto_attach) mechanism
allows pushing the usb (*probe) into the comedi (*auto_attach) and
the usb (disconnect) into the comedi (*detach). This removes the
disconnect between the usb driver and the comedi driver. Now when
the comedi driver is attached it will always have a usb device
associated with it.

This removes the 16 usb device limitation and allows bringing all
the private data into a single struct that can be kzalloc'ed when
the comedi driver is (*auto_attached). It also allows removing the
the sanity checks that make sure a usb device is connected to the

For aesthetic reasons, add some whitespace to the subdevice init.
