Hmm, I could see DMA_ISA_BIT_MASK only replace DMA_BIT_MASK(24)
(but specifically not being conditional upon CONFIG_ISA) without becoming
confusing. Consequently this would eliminate the conditional in the .c
file. And any attempt to eliminate the conditional another way would just
introduce a very similar conditional elsewhere; with this having a single
user (and foreseeably not ever a second one) I would think this would
just make the code less readable.

Or did you have something else in mind that I just don't realize?
