Framebuffer devices that are registered by DRM drivers for fbdev emulation
have a "drmfb" suffix in their name. But makes them to be quite confusing
for drivers that already have "drm" in their name:
$ cat /proc/fb
0 rockchipdrmdrmfb
$ cat /proc/fb
0 simpledrmdrmfb
Also, there isn't a lot of value in adding these "drmfb" suffices to their
names, since users shouldn't really care if the FB devices were registered
by a real fbdev driver or a DRM driver using the fbdev emulation.
What programs should be interested about is if there's a DRM device, and
there are better ways to query that info than reading this procfs entry.
So let's just remove the suffix, which leads to much better device names:
$ cat /proc/fb
0 rockchipdrm
$ cat /proc/fb
0 simpledrm

Changes in v2:
- Just remove the "drmfb" suffix instead of using a different one (tzimmermann).
