staging: comedi: amplc_dio200: set dev->iobase before common attach
Don't pass the I/O base address to `dio200_common_attach()`. The only
thing it does with it is set `dev->iobase` to the passed in value. Do
that before calling `dio200_common_attach()` in order to simplify
upcoming support for different register access methods.
