A code drop from Sony Mobile reveals that the ACX424 panels are
built around the Novatek NT35560 panel controllers so just bite
the bullet and rename the driver and all basic symbols so that
we can modify this driver to cover any other panels also using
the Novatek NT35560 display controller.

Could someone take mercy in reviewing this patch set?

I can offer some patch review back!

I can also offer coffee in person in Sweden, some Star
Wars memorabilia or used mobile phones.

The patches aren't really big, just moving and renaming.
