Subject: [PATCH 5.8 144/232] rtc: pl031: fix set_alarm by adding back call to alarm_irq_enable

From: Sudeep Holla <sudeep.holla@....com>

[ Upstream commit 4df2ef85f0efe44505f511ca5e4455585f53a2da ]

Commit c8ff5841a90b ("rtc: pl031: switch to rtc_time64_to_tm/rtc_tm_to_time64")
seemed to have accidentally removed the call to pl031_alarm_irq_enable
from pl031_set_alarm while switching to 64-bit apis.

Let us add back the same to get the set alarm functionality back.

Fixes: c8ff5841a90b ("rtc: pl031: switch to rtc_time64_to_tm/rtc_tm_to_time64")
