mfd: sec: Add rtc alarm IRQ as platform device resource
By adding the RTC alarm IRQ to the MFD cell as a resource, the child
driver (rtc) can simply query that IRQ, instead of having a lookup
table itself.
This change therefore allows the child driver to be simplified with
regards to determining the alarm IRQ.
