Dear Eric,
Some nit picks where stuff contradicts the coding style.

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
