pnv/xive2: Introduce new capability bits

These bits control the availability of interrupt features : StoreEOI,
PHB PQ_disable, PHB Address-Based Trigger and the overall XIVE
exploitation mode. These bits can be set at early boot time of the
system to activate/deactivate a feature for testing purposes. The
default value should be '1'.

The 'XIVE exploitation mode' bit is a software bit that skiboot could
use to disable the XIVE OS interface and propose a P8 style XICS
interface instead. There are no plans for that for the moment.
