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
if a driver already has "drm" in its name:
$ cat /proc/fb
0 rockchipdrmdrmfb
$ cat /proc/fb
0 simpledrmdrmfb
Instead, let's just add a "-fb" suffix to denote that are DRM drivers FB:
$ cat /proc/fb
0 rockchipdrm-fb
$ cat /proc/fb
0 simpledrm-fb

So what with all the drivers which do _not_ have drm in their name? Also
I'm never sure how much these are uapi or not ...
