jhb dd3faa2109 Rework the DMA handling in ida(4) and add locking to make this driver 
MPSAFE.
- Preallocate a full set of QCBs during attach rather than allocating new
  ones on demand to avoid allocations in the I/O path.
- Remove the explicit bus space tag/handle and use bus_*() on the
  relevant 'struct resource' instead.
- Defer logical drive probing to an intrhook.
- Fix ida_detach() to detach and delete child devices (logical drives).
- Update the DMA handling to support EINPROGRESS by moving the work to
  submit a mapped request into the bus_dma callback routine as well as
  add support for freezing the queue when EINPROGRESS is encountered.
