As discussed previously, these two ARM platforms have no
known remaining users, let's remove them completely.
Subsystem maintainers: feel free to take the driver removals
through your respective trees, they are all independent of
one another. We can merge any remaining patches through the
soc tree.

The platform is getting removed, so there are no remaining
users of this driver.
