Rob Herring ef7ad397fb of: Preserve "of-display" device name for compatibility 
commit 0bb8f49cd2 upstream.

Since commit 241d2fb56a ("of: Make OF framebuffer device names unique"),
as spotted by Frédéric Bonnard, the historical "of-display" device is
gone: the updated logic creates "of-display.0" instead, then as many
"of-display.N" as required.

This means that offb no longer finds the expected device, which prevents
the Debian Installer from setting up its interface, at least on ppc64el.

Fix this by keeping "of-display" for the first device and "of-display.N"
for subsequent devices.
