watchdog: iTCO_wdt: Using existing macro define covers more scenarios
For power management, SET_NOIRQ_SYSTEM_SLEEP_PM_OPS defined for
CONFIG_PM_SLEEP, will point ->suspend_noirq, ->freeze_noirq and
->poweroff_noirq to the same function. Vice versa happens for
->resume_noirq, ->thaw_noirq and ->restore_noirq.
