The vendor name was "toppoly" but other panels and the vendor list
have defined it as "tpo". So let's fix it in driver and bindings.

Yes, it does. But I am only aware of the GTA04 which uses it and
there is a separate fix).

Yes, Tomi should decide if we should keep the old compatible string in
the driver (in second place so to avoid a speed penalty)...
