Not easy from looking at the code. The implementation lying in
rt2x00debug is a common thing.
I considered using "rf" instead, since this isn't used in rt2800. But
the rf register has a 32bits word size, while rfcsr has an 8bits word
size. Also, they do not designate the same thing, even if they're used
the same way.
We could rely on the fact that C struct initialization would be
zeroed, since we're using per-member designated initialization(C99).
It works with the current code because the functions
rt2x00debug_{read,write}_##__name check if the index is > word_count
before doing anything.
I didn't like it because it would then be implicit, but it could do the work.

Oh. Yes, it should be.
