eth: amd: remove NI6510 support (ni65)

Looks like all the changes to this driver had been tree-wide
refactoring since git era begun. The driver is using virt_to_bus()
we should make it use more modern DMA APIs but since it's unlikely
to be getting any use these days delete it instead. We can always
revert to bring it back.
