Hmm, I think there is a small error here.
I either put index in aliases or don't write aliases since the
number of ovl and ovl_2l is one.

I will add 0 and upstae in next version.

Note: 
in mtk_ddp_comp_get_id:
int id = of_alias_get_id(node, mtk_ddp_comp_stem[comp_type]);

(id < 0 || id == mtk_ddp_matches[i].alias_id)) return i;
