We can't do this yet because CONFIG_SPLASH_SCREEN isn't migrated so the
test fails and we drop the bmp logo.  I got this run-time tested and
confirmed on colibri imx6 by my colleague Matt Porter.  So I'm holding
off on _this_ patch (and then the style clean up patch) until I can push
SPLASH_SCREEN migration through.
