soc/amd/stoneyridge: Set missing RTC offsets for day alarm and century
On Linux, in order to set wake alarms >24 hours, the RTC Date Alarm
field must be set to a valid non-zero value. If not, there are two
consequences:
1. Alarms >24 hours don't work
2. The kernel will refuse to enter suspend because it can't resume as
expected to service the alarm.
Since the RTC Date Alarm and RTC AltCentury fields are supported on
Stoneyridge, set them.
This is a mirror of commit 041fcf5902
("soc/amd/picasso/acpi: Set missing RTC offsets") for picasso.
BUG=b:187516317
TEST=On a Chrome OS 'grunt' device, run
`time powerd_dbus_suspend --suspend_for_sec=172800`
and verify the system suspended and woke up after 48 hours
BRANCH=grunt
