Add the device-tree node for the GK20A GPU and leave it disabled by
default. It is the responsability of the bootloader to enable it if the
VPR registers have been programmed such as the GPU can operate.

Are you going to send the corresponding patches for U-Boot to update
the status property if it's initialized VPR?

Yes. But maybe I should wait until upstream Nouveau actually works properly for that? Right now it will probe successfully, but will crash as soon as the GPU is used because there still are memory coherency problems.
