ARM: tegra: Rename GPU node on Tegra124
In order to be able to pass DT schema validation, change the GPU nodes'
unit-address to the standard notation. Previously this was using a "0,"
prefix that originated from a time when the top-level device tree node
contained #address-cells = <2>.
Note that this technically breaks backwards-compatibility with certain
older versions of the U-Boot bootloader because early versions used a
hard-coded DT path lookup to find the GPU node and perform some fixups
on it. However, this was changed to a compatible string based lookup in
April 2016, so it's reasonable to expect people to update U-Boot on the
systems that they want to use this updated kernel DTB with.
