mpreboot: introduce new distro feature
The memory preserving reboot is a feature utilized on IBM systems which
allows a system to be rebooted with its memory preserved. This is
utilized in situations where the host firmware has crashed and put the
processor in an unusable state. The processors are put back in a good
state by rebooting the system. Memory is preserved though so host
firmware can capture the relevant data from memory needed to debug the
cause of the failure.
This feature is implemented across a few different repositories within
OpenBMC so lets create a distro feature to enable it across all of the
software stacks.
