drm/panel-edp: use put_sync in unprepare
Some edp panel requires T10 (Delay from end of valid video data transmitted
by the Source device to power-off) less than 500ms. Using autosuspend with
delay set as 1000 violates this requirement.
Use put_sync_suspend in unprepare to meet the spec. For other cases (such
as getting EDID), it still uses autosuspend.
