arm64: default to the direct mapping in get_arch_dma_ops
Otherwise the direct mapping won't work at all given that a NULL
dev->dma_ops causes a fallback. Note that we already explicitly set
dev->dma_ops to dma_dummy_ops for dma-incapable devices, so this
fallback should not be needed anyway.
Fixes: 356da6d0cd ("dma-mapping: bypass indirect calls for dma-direct")
