They appear to be cargo-cult copying from a design misstep in the very early days of FDT adoption on ARM, which was righted with the "arm,primecell" compatible, and the last trace of the idea finally purged by commit 2ef7d5f342c1 ("ARM, ARM64: dts: drop "arm,amba-bus" in favor of "simple-bus""). As such, they can simply be removed and the DMA-330 nodes fitted into the normal sort order. The node names should be generic, so rename it to "dma-controller".
