[PATCH] drm: sti: fix sub-components bind

[Benjamin Gaignard]

It doesn't change any bindings fields, only remove one level of childs on DT.
Old DTBs may not work but it will impact only very few peoples and no
products so it isn't a problem.
The patch fix driver and DT files so I don't think it could create issues.
