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.
