feat(ff-a): save partitions version during ffa_version

This will be useful later when we may need to consider the version
of a partition when structuring a response to certain FF-A functions.

Also add a call to FFA_VERSION during initialization of the hypervisor
so the SPMC knows the hypervisors implemented version.
