of: property: Fix the semantics of of_is_ancestor_of()
The of_is_ancestor_of() function was renamed from of_link_is_valid()
based on review feedback. The rename meant the semantics of the function
had to be inverted, but this was missed in the earlier patch.
So, fix the semantics of of_is_ancestor_of() and invert the conditional
expressions where it is used.
Fixes: a3e1d1a7f5fc ("of: property: Add functional dependency link from DT bindings")
