fast-reboot: bare bones fast reboot implementation for POWER9
This is an initial fast reboot implementation for p9 which has only been
tested on the Witherspoon platform, and without the use of NPUs, NX/VAS,
etc.
This has worked reasonably well so far, with no failures in about 100
reboots. It is hidden behind the traditional fast-reboot experimental
nvram option, until more platforms and configurations are tested.
