Add a simple getter pm_runtime_is_irq_safe() for quering whether runtime
PM IRQ safe was set or not.

Various bus drivers implementing runtime PM may use choose to suspend
differently based on IRQ safeness status of child driver (e.g. do not
unprepare the clock if IRQ safe is not set).

If you add something to the runtime PM API, you must update the 
documentation file (Documentation/power/runtime_pm.txt) 
correspondingly.

Thank you for pointing this out. I'll fix this and re-spin.

Best regards,
