rtc: pcf85063: do not clear AIE in the interrupt handler
The interrupt handler cleared the alarm interrupt enable (AIE) bit while
acknowledging the alarm flag (AF). This races with process-context updates
of AIE in pcf85063_rtc_alarm_irq_enable() and pcf85063_rtc_set_alarm():
a handler running concurrently can clobber an AIE change.
The RTC core already disables the alarm interrupt after a one-shot alarm
via the .alarm_irq_enable callback, so the handler does not need to touch
AIE at all. Acknowledge AF only and leave AIE management to the core.
