Since there is overlap in supported devices, both modules load, but only
one will bind to a particular device depending on the model and user's
configuration.

amdgpu binds to all display class devices with VID 0x1002 and then
determines whether or not to bind to a device based on whether the
individual device is supported by the driver or not. Log that case, so
users looking at the logs know what is going on.
