fix(spm): not defining load-address in SP config

The FF-A specification has made it such that SPs
may optionally specify their load address in the manifest.

This info was being retrieved to generate some information
for the SPMC manifest. However, it is not a mandatory utility.

This change relaxes the case in which the SP manifest doesn't
have a load address.
