genirq: Fix comment describing suspend_device_irqs()

Browse source 
The kerneldoc comment describing suspend_device_irqs() is currently
misleading, because generally the function doesn't really disable
interrupt lines at the chip level.  Replace it with a more accurate
one.

* During system-wide suspend or hibernation device drivers need to be prevented

* It marks all interrupt lines in use, except for the timer ones, as disabled
