The following series clean up the ioatdma driver and refactors it to support
only ioatdma v3.x devices. This removes a lot of the complexities that
existed to support v1 and v2 based devices as well as v3. Some data structures
are flattened or removed to minimize the abstractions. Now it has an
ioatdma_device that embedes a dma_device, an ioatdma_chan that embeds a
dma_chan and points to an ioatdma_device. All the names are sanitized to
ioat_dma or ioat_chan to make the code more readable. All references to
ioat1 and ioat2 and most of ioat3 are removed. The driver is split into
init.c for init routines, prep.c for dma descriptor preparation routines,
sysfs.c for all sysfs related bits, and dma.c for remaining operation bits.
