PM: Add empty suspend/resume device irq functions
git commit 0a0c5168 "PM: Introduce functions for suspending and resuming device interrupts" introduced some helper functions. However these functions are only available for architectures which support GENERIC_HARDIRQS. Other architectures will see this build error: drivers/built-in.o: In function `sysdev_suspend': (.text+0x15138): undefined reference to `check_wakeup_irqs' drivers/built-in.o: In function `device_power_up': (.text+0x1cb66): undefined reference to `resume_device_irqs' drivers/built-in.o: In function `device_power_down': (.text+0x1cb92): undefined reference to `suspend_device_irqs' To fix this add some empty inline functions for !GENERIC_HARDIRQS.
