Some platforms do not support WAKEUP service by default, we use a shell
script to check the absence of alarm content in /proc/driver/rtc.
The script will validate /proc/driver/rtc when it is not empty and then
check if could find alarm content in it according to the rtc wakealarm
is supported or not.
Requires commit 101ca8d05913b ("rtc: efi: Enable SET/GET WAKEUP services
as optional")
