i82801gx: read RTC status register to prevent IRQ storm

My Thinkpad appeared dead. After investigation, it turned out
    that the RTC Alarm was triggering an RTC PM1 SMI, but the SMI
    handler didn't read the status register, so it was triggered again.

This is a really nasty situation, as it means you have to dissemble
    your Notebook just to unplug the RTC battery.
