Remove an unnecessary animation.

When the notification panel is full-width (small devices
like phones) we can just leave the icons showing all the
time, which saves a little CPU during the
performance-critical shade expand operation.

On sw600dp devices we continue to use DISABLE_SYSTEM_INFO to
smoothly hide the status bar when the notification panel
appears (and show it when the panel is dismissed).
