Fix a glitch in the procfs dumping of whether the alarm IRQ is enabled:
use the traditional name (from drivers/char/rtc.c and many other places)
of "alarm_IRQ", not "alrm_wakeup" (which didn't even match the efirtc
code, which originated that reporting API).
Also, update a few of the RTC drivers to stop providing that duplicate
status, and/or to expose it properly when reporting the alarm state.
We really don't want every RTC driver doing their own thing here...
