This series defines the high level XIVE interface for other drivers
using interrupts in OPAL : PHBs, PSI, NPU, and an operation backend to
prepare ground for the new processors and drivers (P10). The first use
of this backend is for the current P9 driver. Follows cleanups and

The P10 driver is based on top of these new interfaces.
