commit ed17a2bcbb75505bb979e3e8ecb6c5fb2518bf3b upstream.

This keeps the IRQ enabled during system suspend, if the RTC's wakeup
source is enabled. Since the IRQ is not required to wake from shutdown,
continue to add the wakeup source even if registering the wakeirq fails.
See commit 029d3a6f2f3c ("rtc: da9063: add as wakeup source").
