[ Upstream commit 8ab58f6841b19423231c5db3378691ec80c778f8 ] The host1x devices are virtual compound devices and do not perform DMA accesses themselves, so they do not need to be set up for DMA. Ideally we would also not need to set up DMA masks for the virtual devices, but we currently still need those for legacy support on old hardware.
