The _DMA range needs to change depending on the SOC in use, this was part of the problem with enabling DMA by default because there wasn't a clear way to determine the SOC revision in use.
Now that we have an id register for that, we can pick the correct _DMA at runtime. Lets also flip DMA on by default.
