[OE-core] [psplash][PATCH] Add --fbdev option to psplash like --rotation.

[Julien Gueytat]

A new fbdev file is needed and should be overrided if needed.
The number contained in fbdev will be used as X in /dev/fbX.

By overriding fbdev you can have a splash screen on another
framebuffer than /dev/fbO.

You might have to adapt INITSCRIPT_PARAMS in psplash_git.bbappend
in case the framebuffer you want to use is not ready yet.
