AOD - Notif icon location

Support a mode where icons are visible on AOD with the large
clock. This means shifting both smartspace and icons when switching
between large/small clocks.

Also: Continue to remove old keyguard flag
Also: Add a couple logs for smartspace, let
LockscreenSmartspaceController handle disconnect directly
