SPM: Add support for FFA_MEM_PERM_GET/SET

Handle FFA_MEM_PERM_GET and FFA_MEM_PERM_SET interfaces for enabling
SPs to query and set the access rights of their memory regions. These
interfaces are only permitted in the initialization phase thus a new
state variable is being introduced in sp_session. SPs indicate the end
of their initialization phase through the FFA_MSG_WAIT interface.
