Routine Description:
Use Console Control to turn off GOP/UGA based Simple Text Out consoles from going
to the GOP/UGA device. Put up LogoFile on every GOP/UGA device that is a console
Arguments:
LogoFile - File name of logo to display on the center of the screen.
ImageHandle - The driver image handle of the caller. The parameter is used to
optimize the loading of the logo file so that the FV from which
the driver image is loaded will be tried first.
Returns:
EFI_SUCCESS - ConsoleControl has been flipped to graphics and logo
displayed.
EFI_UNSUPPORTED - Logo not found
