VC4's DSI1 has a bug where the AXI connection is broken for 32-bit writes from the CPU, so we use the DMA engine to DMA 32-bit values into registers instead. That sleeps, so we can't do it from the top half. As a solution, use an interrupt thread so that all our writes happen when sleeping is is allowed. v2: Use IRQF_ONESHOT (suggested by Boris) v3: Style nitpicks.
