MFC r354752: Cleanup address range checks in ioat(4).

 - Deduce allowed address range for bus_dma(9) from the hardware version.
Different versions (CPU generations) have different documented limits.
 - Remove difference between address ranges for src/dst and crc.  At least
docs for few recent generations of CPUs do not mention anything like that,
while older are already limited with above limits.
 - Remove address assertions from arguments.  While I do not think the
addresses out of allowed ranges should realistically happen there due to
the platforms physical address limitations, there is now bus_dma(9) to
make sure of that, preferably via IOMMU.
 - Since crc now has the same address range as src/dst, remove crc_dmamap,
reusing dst2_dmamap instead.
