fix(xilinx): handle power down event if SGI not registered
Currently, if SGI is not registered by Linux and power down event from
firmware is received then it's not getting handled in TF-A and core power
down is not happening. Because of that subsystem restart or force power
down without Linux boot is not happening. So, handle power down event in
TF-A if Linux not registered SGI.
