Absolutely.  Its in theory better to always do that, but sometimes it's
just easier to copy type the whole datasheet register map into a driver
so we tend to let it go.

I'd not worry too much on shortening these.  A bit of ugly code never
really hurt anyone if it's just a long define.

Of course, if it makes sense anyway, always good to tidy up naming.
