The logic to allow only one DMA driver in MUSB is currently flawed, because it also allows picking no DMA driver at all and also not selecting PIO mode. Using a choice statement makes this foolproof for now and also simplifies the Makefile. Unfortunately, we will have to revisit this when we start supporting multiple ARM platforms in a single kernel binary, because at that point we will actually need to select multiple DMA drivers and pick the right one at run-time.
