psci: a70x0: a80x0: Hot Plug Cluster Support
MSS implementation does not support cluster power down in case of Hot plug,
therefore we defined MPIDR_AFFLVL1 state to PSCI_LOCAL_STATE_RUN
resulting in max off level set to CPU level.
This definition force execution of core power down instead of
cluster power down In case of Cluster Hot Plug,
including ATF power down cache maintenance
