staging: comedi: amplc_pci224: 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: " DRIVER_NAME portion and use __func__ to show the actual
function name for debugging.
