The era of hand-rolled HIWORD_UPDATE macros is over, at least for those drivers that use constant masks. Remove this driver's very own HIWORD_UPDATE macro, and replace all instances of it with equivalent instantiations of FIELD_PREP_WM16 or FIELD_PREP_WM16_CONST, depending on whether it's in an initializer. This gives us better error checking, and a centrally agreed upon signature for this macro, to ease in code comprehension. Because FIELD_PREP_WM16/FIELD_PREP_WM16_CONST shifts the value to the mask (like FIELD_PREP et al do), a lot of macro instantiations get easier to read. This was tested on an RK3568 ODROID M1, as well as an RK3399 ROCKPro64.
