soc: mediatek: mmsys: Migrate all tables to MMSYS_ROUTE() macro

Now that all of the mmsys routing tables have been fixed,
migrate all of them to use the MMSYS_ROUTE() macro: this
will make sure that future additions to any of the tables
for the currently supported SoCs are compile-time sanity
checked, greatly reducing room for (way too common) mistakes.
