Achin Gupta 61eae524b6 Fix use of stale power states in PSCI standby finisher ... A PSCI CPU_SUSPEND request to place a CPU in retention states at power levels higher than the CPU power level is subject to the same state coordination as a power down state. A CPU could implement multiple retention states at a particular power level. When exiting WFI, the non-CPU power levels may be in a different retention state to what was initially requested, therefore each CPU should refresh its view of the states of all power levels. Previously, a CPU re-used the state of the power levels when it entered the retention state. This patch fixes this issue by ensuring that a CPU upon exit from retention reads the state of each power level afresh.
