staging: comedi: amplc_pci230: remove use of DPRINTK

Use dev_dbg() instead of the DPRINTK macro to output the comedi
debugging information.

The dev_dbg() will prefix the messages appropriately so remove the
"comedi%d: amplc_pci230: " portion and use __func__ to show the
actual function name for debugging.
