There are no more board files defining platform data for this driver so
remove the header and drop the support.

FYI: I'm working on a rework which changes the default for when there
is no DT node. That will allow the removal of the platform data.

It is being built tested at the moment, so i will probably post the
series tomorrow.

There are a number of out of tree x86 boards which use this, flying in
various aircraft, so have a long life, and do get kernel updates.

I'm happy to support this code, and as a PHYLIB Maintainer, it adds
little overhead to my maintenance works. If you really insist, i can
try to get code added to drivers/platform/x86/ which use this.

We typically don't care about out-of-tree board files upstream. Having
users for this struct in mainline would of course be great and a
perfect reason to keep it.
