Most of our register defines follow the convention that if there's a
need for the raw register offset, that one has an underscore sa a
prefix. The define (possibly parametrized) without the underscore is
the one people should normally use, since it will take into account
all the parameters and other potential offsets that are needed.

Fix up the few stragglers that don't follow this convention.
