Staging: aten2011: fix up comments by removing most of them.

This driver was copied from the io_edgeport.c driver, so we need to put
the proper copyright information back on it.

Also, almost all of the function comments are directly from the original
io_edgeport driver, and most of them are either totally wrong now due to
changes, or redundant.  So delete them all so no one gets confused by
anything.
