Inform PHYP of NVDIMM protection by OCC

The OCC is responsible for detecting the EPOW signal
and triggering the save operation on the NVDIMM.
Therefore, if the OCC is not running we are unprotected
from a poweroff event.   PHYP needs to inform the LPARs
using the NV (non-volatile) memory of this state so they
can behave accordingly.

HBRT is responsible for telling PHYP when we get into this state.
There are two ways we can detect this state:
a) HBRT explicitly puts the PM complex into reset
b) PRD detects a specific FIR bit

The message should include this data:
- what state we are in (protected or unprotected)
- which processor is affected

Work for this story will include:
- Definition of the new message
- Creating a utility function to send the message
- Calling utility function to send 'unprotected' message
  inside of all pm reset paths at runtime
