rtc: cmos: Use ACPI alarm for non-Intel x86 systems too
Intel systems > 2015 have been configured to use ACPI alarm instead
of HPET to avoid s2idle issues.
Having HPET programmed for wakeup causes problems on AMD systems with
s2idle as well.
One particular case is that the systemd "SuspendThenHibernate" feature
doesn't work properly on the Framework 13" AMD model. Switching to
using ACPI alarm fixes the issue.
Adjust the quirk to apply to AMD/Hygon systems from 2021 onwards.
This matches what has been tested and is specifically to avoid potential
risk to older systems.
