PM: sleep: wakeirq: Update outdated documentation comments

The comments claiming that dev_pm_*wake_irq*() helpers must be called
with dev->power.lock held and only from rpm_suspend/resume paths are not
accurate any mote, since pm_runtime_force_suspend/resume() call them
locklessly.

Update the comments to match the code.
