In some cases limits are just not needed, in others -- DFLTPHYS is the
right constant to use instead.

DMA tag alignment should be 1 (not 0) when a device can dma at any address.
Rework the DMA handling in ida(4) and add locking to make this driver2012-08-27T17:24:07ZJohn Baldwinjhb@FreeBSD.org2012-08-27T17:24:07Zurn:sha1:6b5b57ae9f8f109f9224d65e331d1177ceaba592
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.

PCI device attachment.
- There's no need to overwrite the default device method with the default2011-11-22T21:28:20ZMarius Stroblmarius@FreeBSD.org2011-11-22T21:28:20Zurn:sha1:4b7ec27007570e0ce4fe9dbb447e7afc131b487a
one. Interestingly, these are actually the default for quite some time
(bus_generic_driver_added(9) since r52045 and bus_generic_print_child(9)
since r52045) but even recently added device drivers do this unnecessarily.
Discussed with: jhb, marcel
- While at it, use DEVMETHOD_END.
Discussed with: jhb
- Also while at it, use __FBSDID.
