Subject: [PATCH 2/2] include/bitmap.h: add new functions to documentation

I found these functions only by chance although I was looking exactly
for something like them. So, add them to the list of functions to make
them more visible.

Fixes: e837dfde15a4 ("bitmap: genericize percpu bitmap region iterators")
