feat(FF-A): implement FFA_SPM_ID_GET interface
If FFA_SPM_ID_GET is invoked at the secure virtual FF-A instance
(a secure partition) return the SPMC id. The SPMC id is queried by
the SPMC to the SPMD by calling FFA_ID_GET or by the Hypervisor to
the SPMD by calling FFA_SPM_ID_GET. Introduce plat_ffa module to
allow for the SPMC and hypervisor specific code.
