The last time a similar patch was proposed[1], I pointed out that U-Boot
uses the node name to enable the node, so this change will break GPU
functionality on this board. U-Boot has since been updated to find the
node to enable using compatible value rather than hard-coding the node
name, but this doesn't help people with existing bootloader binaries;
kernel changes shouldn't force them to upgrade the bootloader. I think
the DT node names are part of the ABI and shouldn't be changed. We can
fix this for completely new SoCs, but not existing SoCs.
