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

phy-rockchip-samsung-dcphy is actually an exemplary example, where the
similarities to FIELD_PREP were spotted and the driver local macro has
the same semantics as the new FIELD_PREP_WM16 hw_bitfield.h macro.

Still, get rid of FIELD_PREP_HIWORD now that a shared implementation
exists, replacing the two instances of it with FIELD_PREP_WM16. This
gives us slightly better error checking; the value is now checked to fit
in 16 bits.
