On POWER9, the KVM XIVE device uses priority 7 for the escalation
interrupts. On POWER10, the host can use a reduced set of priorities
and KVM will configure the escalation priority to a lower number. In
any case, the guest is allowed to use priorities in a single range :
[ 0 .. (maxprio - 1) ].
Introduce a 'hv-prio' property to represent the escalation priority
number and use it to compute the "ibm,plat-res-int-priorities"
property defining the priority ranges reserved by the hypervisor.
