x86: fix RTC_AIE with CONFIG_HPET_EMULATE_RTC
In the current code, RTC_AIE doesn't work if the RTC relies on CONFIG_HPET_EMULATE_RTC because the code sets the RTC_AIE flag in hpet_set_rtc_irq_bit(). The interrupt handles does accidentally check for RTC_PIE and not RTC_AIE when comparing the time which was set in hpet_set_alarm_time(). I now verified on a test system here that without the patch applied, the attached test program fails on a system that has HPET with 2.6.24-rc7-default. That's not critical since I guess the problem has been there for several kernel releases, but as the fix is quite obvious. Configuration is CONFIG_RTC=y and CONFIG_HPET_EMULATE_RTC=y.
