We can't simply override arm_dma_ops with xen_dma_ops because devices are allowed to have their own dma_ops and they take precedence over arm_dma_ops. When running on Xen as initial domain, we always want xen_dma_ops to be the one in use. We introduce __generic_dma_ops to allow xen_dma_ops functions to call back to the native implementation.
