feat(ff-a): allow ffa_run forwarding to secure world.

An ffa_run is needed when there are secondary secure parititions with
multiple execution contexts. Power management does not wake up those
execution contexts into their wait loops, so an ffa_run is necessary.
This is similar to the infrastructure tf-a-tests has to enable running
multiple secure partitions.
