Subject: [PATCH] arm64: tegra: Fix address of Tegra264 main GPIO controller

The 64-bit address of the main GPIO controller on Tegra264 is
0x810c300000. The main GPIO controller was incorrectly added under the
bus@0 node instead of the bus@8100000000 node breaking the boot on
Tegra264. Fix this by moving to main GPIO controller node under
bus@8100000000.

Fixes: c70e6bc11d20 ("arm64: tegra: Add Tegra264 GPIO controllers")
