media: synopsys: hdmirx: replace macros with bitfield variants

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

Replace the UPDATE macro with bitfield.h's FIELD_PREP, to give us
additional error checking.

Also, replace the HIWORD_UPDATE macro at the same time with the new
FIELD_PREP_WM16 macro in hw_bitfield.h, which also gives us additional
error checking.

The UPDATE/HIWORD_UPDATE macros are left as wrappers around the
replacement macros, in order to not rock the boat too much, and keep the
changes easy to review.
