SynQuacer SoC contains a Cortex-M3 System Control Processor(SCP) which manages system power. This commit modifies the PSCI system_off handling to call SCMI, same as other PSCI calls. System power-off is done by turing off the ATX power supply through GPIO, this operation is transferred to SCP. Note that this commit modifies only the SCMI case, obsolete SCPI implementation is not updated.
