Subject: [PATCH] arm64: tegra: p2180: 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
Tegra210 devices already explicitly enable the gpu, so make p2180 match.
