Is the fallthrough annotation really needed?

Just to shut up compiler warnings, and even that I haven't seen myself.

I have seen a number of patches adding either comments or this 
annotation in the core NCR5380 driver (which Finn maintains, who 
suggested this annotation to an earlier version of the Q40/Atari io_mm.h 
patch), so adding annotations appears to be encouraged now.

I personally think these annotations are over the top generally, but 
I've learned to program when computed goto statements were still en vogue.

In this particular case, there can be no doubt that the fallthrough is 
intentional, so on balance, I'll remove those annotations as well 
(unless Finn strongly objects?).
