This adds a put_tce() callback to the SPAPR TCE TABLE device class.
The new callback allows to have different IOMMU types such as upcoming
VFIO IOMMU and it will be used more by the upcoming Multi-TCE support.

This reworks the H_PUT_TCE handler to make use of the new put_tce()
callback.

Looks reasonable, but not needed for 2.0 unless a second implementation
comes up.

Thanks! What is now? It goes to your ppc-next? Or Alex's ppc-next? I am
confused with recent activity in PPC field :)

I am currently on vacation and Andreas has fortunately offered to help out with collecting bug fixes for the 2.0 release. We are in the stabilization phase for 2.0 right now, so from now on until the release there should only be bug fixes landing in the tree :).

I'll pick up everything that was left behind (features, refactorings, etc) after the 2.0 release ;).

Greetings from Malaysia,

Alex
