amd/stoneyridge: Clear SMI_EVENT_STATUS when entering S3/S5
disable_all_smi_status() was not clearing SMI_EVENT_STATUS. This caused
us to complain in the eventlog (ELOG_SLEEP_PENDING_GPE0_WAKE) and then
wake early from sleep when waiting for a cr50 reset to turn on a cr50
update.
BUG=b:121203745
TEST=Careena remains in S5 until cr50 reset after cr50 update, and
ELOG_SLEEP_PENDING_GPE0_WAKE is no longer seen in eventlog.
