net: stmmac: dwmac-rk: 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.

Like many other Rockchip drivers, dwmac-rk has its own HIWORD_UPDATE
macro. Its semantics allow us to redefine it as a wrapper to the shared
hw_bitfield.h FIELD_PREP_WM16 macros though.

Replace the implementation of this driver's very own HIWORD_UPDATE macro
with an instance of FIELD_PREP_WM16 from hw_bitfield.h. This keeps the
diff easily reviewable, while giving us more compile-time error
checking.

The related GRF_BIT macro is left alone for now; any attempt to rework
the code to not use its own solution here would likely end up harder to
review and less pretty for the time being.
