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.

Doesn't this break backward compatibility with existing DT ?

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

DT is supposed to be an ABI. In theory at least, one could boot a GTA04 with 
an existing DT and a new kernel, and no regression should be noticed. There 
could also be other devices using this panel that you are not aware of.

For how to apply the theory to real life, I'll defer to Tomi :-)

Yes, indeed...

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