[PULL 29/45] spapr/xive: use SPAPR_IRQ_IPI to define IPI ranges exposed

From: David Gibson
Subject: [PULL 29/45] spapr/xive: use SPAPR_IRQ_IPI to define IPI ranges exposed to the guest
Date: Tue, 17 Mar 2020 21:04:07 +1100

From: Cédric Le Goater <address@hidden>

The "ibm,xive-lisn-ranges" defines ranges of interrupt numbers that
the guest can use to configure IPIs. It starts at 0 today but it could
change to some other offset. Make clear which IRQ range we are
exposing by using SPAPR_IRQ_IPI in the property definition.
