Eliminate psci_suspend_context array
psci_suspend_context is an array of cache-line aligned structures containing the single power_state integer per cpu. This array is the only structure indexed by the aff_map_node.data integer. This patch saves 2KB of BL3-1 memory by placing the CPU power_state value directly in the aff_map_node structure. As a result, this value is now never cached and the cache clean when writing the value is no longer required. Fixes ARM-software/tf-issues#195 Change-Id: Ib4c70c8f79eed295ea541e7827977a588a19ef9b
