Remove some commented out code. Some of it uses constructs that don't
exist in the driver, and probably come from the source code for the MS
Windows driver.

It might be a good idea to add a comment about the magic 0x0800 and 0xc000 values:

word2 |= 0x0800; /* offset */
word3 |= 0xc000; /* gain */

Fair enough.

Wish I could find a register map for this board. I sent an email to Measurement Computing
to see if one is available.

I think the board was made by IOTech and added to Measurement Computing's catalog, and the Windows driver appears to have been done by IOTech too.
