ioat: move to drivers/dma/ioat/ When first created the ioat driver was the only inhabitant of drivers/dma/. Now, it is the only multi-file (more than a .c and a .h) driver in the directory. Moving it to an ioat/ subdirectory allows the naming convention to be cleaned up, and allows for future splitting of the source files by hardware version (v1, v2, and v3).

ioat2,3: convert to a true ring buffer Replace the current linked list munged into a ring with a native ring buffer implementation. The benefit of this approach is reduced overhead as many parameters can be derived from ring position with simple pointer comparisons and descriptor allocation/freeing becomes just a manipulation of head/tail pointers. It requires a contiguous allocation for the software descriptor information. Since this arrangement is significantly different from the ioat1 chain, move ioat2,3 support into its own file and header. Common routines are exported from driver/dma/ioat/dma.[ch].
