video: Support showing the U-Boot logo

Show the U-Boot logo by default. This is only 7KB in size so seems like
a useful default for boards that enable a display.

If SPLASH_SCREEN is enabled, it is not enabled by default, so as not to
conflict with that feature.

Also disable it for tests, since we don't want to complicate the output.
