Send subsystem restart notification to firmware when TF-A receives system reset PSCI call. On receiving subsystem restart call, firmware will send CPU idle callback to TF-A for powering down all cores. Wait for CPU idle callback from firmware and raise power down request to all cores after it receives CPU idle callback to power down core.
