Subject: [PATCH] rtc: pl031: fix alarm support

Commit 75a472845196 ("rtc: pl031: switch to rtc_time64_to_tm/rtc_tm_to_time64")
adjusted driver to the new API, but during the conversion a call to enable
alarm irq in set_alarm() was lost. Restore it, what fixes alarm support in
the PL031 RTC driver.
