Curious why the "(*{rd, wr}_32)()" are not removed together with others
in this patch?
Also, it would be better to put the removal of the udevice {rd, wr}*
callbacks in another new patch? As the tittle of this patch is for
cleaning the nvif, while udevice layer uses the nvkm_{rd,wr}, which
directly use io{read, write}*. I suppose it is not tied to nvif.
