parentncr5380: Remove command list debug code (diff)

ncr5380: Remove H_NO macro and introduce dsprintk
Replace all H_NO and some HOSTNO macros (both peculiar to atari_NCR5380.c) with a new dsprintk macro that's more useful and more consistent. The new macro avoids a lot of boilerplate in new code in subsequent patches. Keep NCR5380.c in sync. Remaining HOSTNO macros are removed as side-effects of subsequent patches.
