The PSCI CPU suspend code isn't aware of the PMR vs DAIF game, resulting in a system that locks up if entering CPU suspend with GICv3 pNMI enabled. To save the day, teach the suspend code about our new cpuidle context helpers, which will do everything that's required just like the usual WFI cpuidle code. This fixes my Altra system, which would otherwise lock-up at boot time when booted with irqchip.gicv3_pseudo_nmi=1.
