MT2701, MT2712 and MT8173 were relying on a "default" DDP I/O routing table, describing all of the possible connections between display block components: while this is definitely working it's suboptimal for the actual routing description, as we may be enabling outputs and inputs that are not needed, possibly impacting on actual DDP performance other than slightly prolonging boot times by having to parse a table that is bigger than needed. Seen that all of the other supported SoCs have got their own table and seen that a comment in mtk-mmsys.h explicitly mentions that the wanted way is to have one table per SoC, create a new routing table that is specifically tailored to MT8173 and, while at it, remove mentions to said SoC from the comment in mtk-mmsys.h.
