  we use a fixed allocation of BDMA streams. We previously dynamically
  allocated these, but bugs in the chip make that unreliable. This is
  a tested set of allocations that is known to work on boards that are
  using all 3 of ADC3, I2C4 and SPI6. They are the only peripherals
  that can use BDMA, so fixed allocation is possible as we have 8
  streams and a maximum of 6 needed.

  The layout is chosen to:

   - avoid stream 0, as this doesn't work on ADC3 or SPI6_RX for no known reason
   - leave a gap between the peripheral types, as we have previously found that we sometimes
     lost SPI6 BDMA completion interrupts if SPI6 and I2c4 are neighbours
