s2ram: add arch irq disable/enable hooks
After some more discussion this patch replaces it: From: Johannes Berg <johannes@sipsolutions.net> Subject: suspend: add arch irq disable/enable hooks For powermac, we need to do some things between suspending devices and device_power_off, for example setting the decrementer. This patch allows architectures to define arch_s2ram_{en,dis}able_irqs in their asm/suspend.h to have control over this step.
