Add the wfi, cpu idle and cpu deep idle power states support for the Armada XP SoCs. All the latencies and the power consumption values used at the "armada_370_xp_idle_driver" structure are preliminary and will be modified in the future after running some measurements and analysis. Based on the work of Nadav Haklai.
