Subject: [PATCH] arm64: dts: tegra: fix APB DMA controller node name

The APB DMA controller node is currently named "dma@...20000",
but according to the binding
Documentation/devicetree/bindings/dma/nvidia,tegra20-apbdma.yaml
the node name should be "dma-controller".

Update the node name to match the binding and fix dtbs_check
warnings.
