We can add things when we need them. This mecanism is to be used by
platforms who register of_device's for the PHBs. Currently, this will
only happen with Cell, so I only need to deal with what's there (I could
even remove 'ht' from the list :-)

As more platforms want to use it, they can fine-tune the list and probe
function.
