Start from object_property_add_link().

link<foo> properties represent a cross-reference to an object of type
foo, which is representated as a pointer in C and as a textual canonical
path representation in QMP. By contrast we model child<foo> properties
as value fields (cf. SoC/MPCore modeling discussions) and they actually
form the canonical paths used by link<> properties.
