[PATCH 1/2] fbdev/offb: Update expected device name

[Cyril Brulebois <cyril@debamax.com>]

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.

It might be better to iterate on all possible nodes, but updating the
hardcoded device from "of-display" to "of-display.0" is confirmed to fix
the Debian Installer at the very least.
