rtc_irq_set_freq() requires power-of-two and associated kerneldoc
RTC periodic IRQs are only defined to work for 2^N Hz values. This patch
moves that validity check into the infrastructure, so drivers don't need to
check it; and adds kerneldoc for the two interface functions related to
periodic IRQs. (One of which was quite mysterious until its first use was
recently checked in!)
