[yocto] [PATCH] psplash: Add custom bar image and color options.

[Julian Scheel]

To make more use of the option to overwrite the splash image this adds the
possibility to overwrite the bar image as well as the color header file to
make a consistent splash screen even when a different background color is
desired.
