phy: rockchip-samsung-dcphy: switch to FIELD_PREP_WM16 macro
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.
