The era of hand-rolled HIWORD_UPDATE macros is over, at least for those
drivers that use constant masks.

Replace the implementation of this driver's HIWORD_UPDATE macro with an
instance of HWORD_UPDATE_CONST. The const variant is chosen here because
some of the header defines are then used in initializers.

This gives us some compile-time error checking, while keeping the diff
very small and easy to review.
