Cédric Le Goater 0df68c7ed6 ppc/pnv: Rework cache watch model of PnvXIVE 
When the software modifies the XIVE internal structures, ESB, EAS,
END, NVT, it also must update the caches of the different XIVE
sub-engines. HW offers a set of common interface for such purpose.

The CWATCH_SPEC register defines the block/index of the target and a
set of flags to perform a full update and to watch for update
conflicts.

The cache watch CWATCH_DATAX registers are then loaded with the target
data with a first read on CWATCH_DATA0. Writing back is done in the
opposit order, CWATCH_DATA0 triggering the update.

The SCRUB_TRIG registers are used to flush the cache in RAM, and to
possibly invalidate it. Cache disablement is also an option but as we
do not model the cache, these registers are no-ops

Today, the modeling of these registers is incorrect but it did not
impact the set up of a baremetal system. However, running KVM requires
a rework.
