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 FIELD_PREP_WM16_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.
