libpore: P10 stop-api support

Update libpore with P10 STOP API. Add minor changes to make
P9 stop-api and P10 stop-api to co-exist in OPAL.

These calls are required for STOP11 support on P10.
STIOP0,2,3 on P10 does not lose full core state or scoms.
stop-api based restore of SPRs or xscoms required only
for STOP11 on P10.

STOP11 on P10 will be a limited lab test/stress feature
and not a product feature. (Same case as P9)
