OMAP3: PM: Disable interrupt controller AUTOIDLE before WFI
OMAP interrupt controller goes to unknown state when there is right
combination of l3,l4 sleep/wake-up transitions, l4 autoidle in
interrupt controller and some interrupt. When this happens, interrupts
are not delivered to ARM anymore and ARM will remain in WFI (wait for
interrupt) until interrupt controller is forced to wake-up
(i.e. lauterbach).
