This reverts commit b3484d2b03e4c940a9598aa841a52d69729c582a.
That change attempted to improve the DRM drivers fbdev emulation device names to avoid having confusing names like "simpledrmdrmfb" in /proc/fb.
But unfortunately there are user-space programs, such as pm-utils that query that information and so broke after the mentioned commit. Since the names in /proc/fb are used programs that consider it an ABI, let's restore the old names even when this lead to silly naming like the one mentioned above as an example.
