drm/mediatek: fix OF sibling-node lookup
commit ceff2f4dcd44abf35864d9a99f85ac619e89a01d upstream.
Use the new of_get_compatible_child() helper to lookup the sibling
instead of using of_find_compatible_node(), which searches the entire
tree from a given start node and thus can return an unrelated (i.e.
non-sibling) node.
This also addresses a potential use-after-free (e.g. after probe
deferral) as the tree-wide helper drops a reference to its first
argument (i.e. the parent device node).
While at it, also fix the related cec-node reference leak.
