[patch 04/38] device irq power management

[Martin Schwidefsky]

From: Heiko Carstens <heiko.carstens@xxxxxxxxxx>

On architectures without GENERIC_HARDIRQS there are no device irqs
to suspend or resume. Add an #ifdef to replace suspend_device_irqs()
and resume_device_irqs() with an empty inline function in that case.
