[PATCH 2/4] ARM: tegra: venice2: Add GK20A GPU DT node

[Alexandre Courbot]

From: Thierry Reding <treding@xxxxxxxxxx>

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