John Baldwin 6b5b57ae9f 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.
