Soby Mathew abd2aba99e CSS: Allow system suspend only via PSCI SYSTEM_SUSPEND API ... The CSS power management layer previously allowed to suspend system power domain level via both PSCI CPU_SUSPEND and PSCI SYSTEM_SUSPEND APIs. System suspend via PSCI CPU_SUSPEND was always problematic to support because of issues with targeting wakeup interrupts to suspended cores before the per-cpu GIC initialization is done. This is not the case for PSCI SYSTEM_SUSPEND API because all the other cores are expected to be offlined prior to issuing system suspend and PSCI CPU_ON explicit calls will be made to power them on. Hence the Juno platform used to downgrade the PSCI CPU_SUSPEND request for system power domain level to cluster level by overriding the default `plat_psci_pm_ops` exported by CSS layer. Given the direction the new CSS platforms are evolving, it is best to limit the system suspend only via PSCI SYSTEM_SUSPEND API for all CSS platforms. This patch makes changes to allow system suspend only via PSCI SYSTEM_SUSPEND API. The override of `plat_psci_ops` for Juno is removed.
