[PATCH] rtc-sa1100 rtc_wklarm.enabled bugfixes

Some rtc-sa1100 bugfixes:

 - The read_alarm() method reports the rtc_wkalrm.enabled field properly.
   This patch is already in the handhelds.org tree.

 - And the set_alarm() method now handles that flag correctly, rather than
   making mismatched {en,dis}able_irq_wake() calls, which trigger runtime
   warning messages.  (Those calls are best made in suspend/resume methods.)

Note that while this SA1100/PXA RTC is fully capable of waking those ARM
processors from sleep states, that mechanism isn't properly supported on
either processor family, or in this driver.  Some boards have board-specific
PM glue providing partial workarounds for the weak generic PM support.
