powerpc/powernv: Make it possible to skip the IRQHAPPENED check in power7_nap()
To support split core we need to be able to force all secondaries into nap, so the core can detect they are idle and do an unsplit. Currently power7_nap() will return without napping if there is an irq pending. We want to ignore the pending irq and nap anyway, we will deal with the interrupt later.
