ffb drm dead code removal..

[Dave Airlie]

Dave,
	I want to apply the following to the ffb DRM it is dead code as
the DRM doesn't use the macro anymore... if you have no issues I'll send
it on to Linus..

I've no way to build the ffb driver at all at the moment, if anyone builds
sparc kernels with ffb regularly I don't suppose you could checkout DRM
cvs and build it against the kernel to see if it still builds...

Dave.
