PATCH 1/1 arm64: tegra: p3310: Explicitly enable GPU

The gpu node originally was explicitly left disabled as it was expected for the bootloader to enable it. However, this is only done in u-boot. If u-boot is not in the boot chain, this will never be enabled. Other Tegra186 devices already explicitly enable the gpu, so make p3310 match.
