It helps for consistency of style with all the other definitions here where
some other registers don't have such trivial mappings of fields to C base types.
I know that using bitfields in arch independent code is fraught with problems.
But these definitions are for the bits in Intel MSRs (model specific registers).
This seems to be an open & shut case that this code is never going to be
used on some other architecture.
