[PATCH] powerpc/xics: Adjust interrupt receive priority for offline cpus

Offline CPUs need to receive IPIs through XIVE when they are
in stop state and wakeup from that state.

Reduce interrupt receive priority in order to receive XIVE
wakeup interrupts when in offline state.

LOWEST_PRIORITY would allow all interrupts to be delivered
as wakeup events.
