fvp: add Cactus/Ivy Secure Partition information

Add load address and UUID in fw config dts for Cactus and Ivy which are
example SP's in tf-test repository.

For prototype purpose these information is added manually but later on
it will be updated at compile time from SP layout file and SP manifests
provided by platform.
