rtc-cmos: Add an alarm disable quirk
commit d5a1c7e3fc38d9c7d629e1e47f32f863acbdec3d upstream.
41c7f7424259f ("rtc: Disable the alarm in the hardware (v2)") added the
functionality to disable the RTC wake alarm when shutting down the box.
However, there are at least two b0rked BIOSes we know about:
https://bugzilla.novell.com/show_bug.cgi?id=812592
https://bugzilla.novell.com/show_bug.cgi?id=805740
where, when wakeup alarm is enabled in the BIOS, the machine reboots
automatically right after shutdown, regardless of what wakeup time is
programmed.
Bisecting the issue lead to this patch so disable its functionality with
a DMI quirk only for those boxes.
