of: Preserve "of-display" device name for compatibility
commit 0bb8f49cd2cc8cb32ac51189ff9fcbe7ec3d9d65 upstream.
Since commit 241d2fb56a18 ("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.
