staging: comedi: das08: remove board register map comments

Browse Source 
The "das08" module contains some comments outlining the register maps
for some of the ISA boards supported by this module in combination with
the "das08_isa" module.  The comments are somewhat sporadically placed,
don't detail all the boards, and don't use the preferred block comment
style.  If anywhere, they should probably be in the "das08_isa" module.
Just remove them.  The comments for the register macros indicate which
boards they apply to anyway, so we don't lose much information.
