Soby Mathew c0aff0e0b4 PSCI: Add SYSTEM_SUSPEND API support This patch adds support for SYSTEM_SUSPEND API as mentioned in the PSCI 1.0 specification. This API, on being invoked on the last running core on a supported platform, will put the system into a low power mode with memory retention. The psci_afflvl_suspend() internal API has been reused as most of the actions to suspend a system are the same as invoking the PSCI CPU_SUSPEND API with the target affinity level as 'system'. This API needs the 'power state' parameter for the target low power state. This parameter is not passed by the caller of the SYSTEM_SUSPEND API. Hence, the platform needs to implement the get_sys_suspend_power_state() platform function to provide this information. Also, the platform also needs to add support for suspending the system to the existing 'plat_pm_ops' functions: affinst_suspend() and affinst_suspend_finish().
