The era of hand-rolled HIWORD_UPDATE macros is over, at least for those drivers that use constant masks.
The inno-hdmi driver's own HIWORD_UPDATE macro is instantiated only twice. Remove it, and replace its uses with HWORD_UPDATE. Since HWORD_UPDATE shifts the value for us, we replace using the mask as the value by simply using 1 instead. With the new HWORD_UPDATE macro, we gain better error checking and a central shared definition. This has been compile-tested only as I lack hardware this old, but the change is trivial enough that I am fairly certain it's equivalent.
