drivers/rtc: remove IRQF_DISABLED 

Since commit e58aa3d2d0 ("genirq: run irq handlers with interrupts
disabled") we run all interrupt handlers with interrupts disabled and we
even check and yell when an interrupt handler returns with interrupts
enabled - see commit b738a50a20 ("genirq: warn when handler enables
interrupts").

So now this flag is a NOOP and can be removed.
