arm64: Make default dma_ops to be noncoherent
Currently arm64 dma_ops is by default made coherent which makes it opposite in default policy from arm. Make default dma_ops to be noncoherent (same as arm), as currently there aren't any dma-capable drivers which assumes coherent ops Signed-off-by: Ritesh Harjani <ritesh.harjani@gmail.com> Acked-by: Will Deacon <will.deacon@arm.com> Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
