I want to correct what i said. For the irq register/unregister i think
can be done at open/release. But for clock enable/disable, i do not
think so. If clock is disabled, as i think RTC will not work. User API
still use open->get_time->close for "date" command. It means that RTC
will not return correct date to user.

"I think" is not good enough for patches like this.  Please test it.

On SA11x0 and PXA platforms, the clock for the sa1100-rtc is a dummy
clock; it has no effect.  For MMP, I don't have access to the TRMs so
that's something you're going to have to find out.
