Subject: [PATCH] arm64: tegra: p3310: Explicitly enable GPU

From: Aaron Kling <webgeek1234@...il.com>

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.
