[PATCH 4/5] Staging: comedi: addi-data: tidy up timer register map defines in hwdrv_apci1564.c

This patch for hwdrv_apci1564.c fixes the register map defines for the
timer 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.
