staging: comedi: pcl730: add support for Diamond Systems PC/104 modules

The Diamond Systems OPMM-1616-XT board is a PC/104 module with 16
optoisolated inputs and 16 relay outputs.

The PEARL-MM-P board is a PC/104 module with 16 relay outputs.

Both of these boards can be supported by the pcl730 driver.
