resume_device_irqs - enable interrupt lines disabled by suspend_device_irqs()

suspend_device_irqs - disable all currently enabled interrupt lines

During system-wide suspend or hibernation device drivers need to be prevented from receiving interrupts and this function is provided for this purpose. It marks all interrupt lines in use, except for the timer ones, as disabled and sets the IRQS_SUSPENDED flag for each of them.
