I never got around to replying to this: the interface to the DPAUX FIFO
isn't a single register that uses non-incrementing writes, but rather a
set of five registers that map the entire FIFO linearly. So it can't be
written to with writesl() or read from with readsl().

The function names are slightly confusing in this regard. But the write
destination is still a FIFO, hence this choice of name.
