x86, s3: Sync platform stamps at time suspend.

platform_timer_stamp and stime_platform_stamp are synced
to platform timer in time calibration (1s interval), and
thus doesn't reflect the latest value. If they're not
synced at time suspend, the offset can be lost after S3
resume. Average 0.8s lag-behind is observed for each S3
action, which accumulates to TOD inaccuracy.
