Subject: [PATCH 2/5] Staging: comedi: addi-data: tidy up digital output register map defines in hwdrv_apci1564.c

This patch for hwdrv_apci1564.c fixes the register map defines for the
digital output registers such that they are all the real offsets to each
register, rather than a mix of real offsets and adders to those offsets.
Additionally, the defines have been renamed to assist with shortening
some lines in excess of 80 characters.

Further, some of the old defines were being used incorrectly in the
i_APCI1564_Reset() function.  Upon swapping the old defines out for the
new ones in this function, their use has been corrected.
