System reset IPI facility and Mambo implementation
Add an opal call OPAL_SIGNAL_SYSTEM_RESET which allows system reset
exceptions to be raised on other CPUs and act as an NMI IPI. There
is an initial simple Mambo implementation, but allowances are made
for a more complex hardware implementation.
This API is based on the POWER8 implementation from Alistair Popple.
