On P9 and 10, the real hardware defines the PQ state of the PSIHB
interrupts to be 0b00. Qemu defaults to 0b01.

It doesn't matter to skiboot, which doesn't rely on it and explicitly
masks the interrupts during intialization. But this patch fixes it,
just in case some other hypervisor checks it.


Frederic Barrat (2):
  pnv/xive: Add property on xive sources to define PQ state on reset
  pnv/psi: Initialize the PSIHB interrupts to match hardware
