bootconfig: Reject subkey and value on same parent key
Reject if a value node is mixed with subkey node on same parent key node. A value node can not co-exist with subkey node under some key node, e.g. key = value key.subkey = another-value This is not be allowed because bootconfig API is not designed to handle such case.

In both styles, same key words are automatically merged when parsing it
at boot time. So you can append similar trees or key-values.
+Note that a sub-key and a value can not co-exist under a parent key.
