reason:
1.there will more and more Mediatek Soc upstream, and the display path
connection function mtk_mmsys_ddp_mout_en, mtk_mmsys_ddp_sel_in and
mtk_mmsys_ddp_sout_sel will complicated more and more,
2. many of the connection are only used in some SoC, and useless for
other SoC and not readable,
3. if we add a new SoC connection, we need check is this affect other
Soc,

can not reused, that why need add mmsys private data like before
version.
but that still not a good idea.
the next path like this will be more readable, and more easy to maintain
