[PATCH] drm/fb-helper: improve DRM fbdev emulation device names

[Javier Martinez Canillas]

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
