rtc-at91rm9200: avoid spurious irqs
This fixes kernel http://bugzilla.kernel.org/show_bug.cgi?id=11112 (bogus RTC update IRQs reported) for rtc-at91rm9200 by scrubbing old IRQ status before enabling IRQs. It also removes nonfunctional periodic IRQ support from this driver; only update IRQs are reported, or provided by the hardware. I suspect some other RTCs probably have versions of #11112; it's easy to overlook, since most non-RTC drivers don't care about spurious IRQs: they're not reported to userspace.
