Move S01apsplash to S12apsplash for TFTs
psplash works just fine on the TFT but the framebuffer device - /dev/fb1 - doesn't show up until after mdev is run. So we need to move this init script to after S11dev, just to be sure. That leaves a short blank display time but it's hardly noticable.
The best way to do this is not make the software figure it out itself. We know when we'll be using a TFT for system builds so just tell psplash packaging to do the right then at build time.
