v3d: replace all TODO around for FIXME

Even if there is a slight difference of meaning between FIXME and
TODO, at some point we agreed to use just FIXME for all pending things
to do, just to make it easier to grepping for things that can be done.

And after all, one could argue that is there is something pending TO
DO, is that needs FIXING.
