core: POWER9 implement OPAL_SIGNAL_SYSTEM_RESET
This implements OPAL_SIGNAL_SYSTEM_RESET, using scom registers to
quiesce the target thread and raise a system reset exception on it.
It has been tested on DD2 with stop0 ESL=0 and ESL=1 shallow power
saving modes.
DD1 is not implemented because it is sufficiently different as to
make support difficult.
