of: Preserve "of-display" device name for compatibility
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.
