ioat3: split ioat3 support to its own file, add memset

Up until this point the driver for Intel(R) QuickData Technology
engines, specification versions 2 and 3, were mostly identical save for
a few quirks. Version 3.2 hardware adds many new capabilities (like
raid offload support) requiring some infrastructure that is not relevant
for v2. For better code organization of the new funcionality move v3
and v3.2 support to its own file dma_v3.c, and export some routines from
the base files (dma.c and dma_v2.c) that can be reused directly.

The first new capability included in this code reorganization is support
for v3.2 memset operations.

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].

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).
