SystemUI: Don't use horizontal quick settings on large screens

On large screens such as tablets, the horizontal quick settings isn't necessary as we have enough room for the normal quick settings and media player.
It also seems to have issues on large screens, on my v1awifi I can't swipe to a different quick settings page and the media player album art overlaps the media controls.
