Yeah I'm not taking any more of new platform data like this,
this all is already very trivial to do with device tree
directly in the driver. Adding this would make the pains of
moving to device tree based booting just more of a pain and
guess who has to deal with all of that.

For the hwrng platform data makes still sense even for the
device tree as we don't have any better way currently to do
the SMC callbacks.
