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().

This patch is against 2.6.24-rc5-mm1.
