radeon: Delete DRI1 screen init code and thus support for !kernel_mm.

It's past time, and it was going to get in the way of the renderbuffer
mapping refactor.  We dropped all the other DRI1 drivers for this
release, and I can't imagine anybody supporting DRI1 radeon classic in
a new release of Mesa.

Cleanup of the resulting dead code to follow.
