ioat3: dca and raid operations are incompatible
RAID operations cause a system hang on platforms with DCA
(Direct-Cache-Access) enabled. So turn off RAID capabilities in this
case.

ioat: define descriptor control bit-field
This cleans up a mess of and'ing and or'ing bit definitions, and allows
simple assignments from the specified dma_ctrl_flags parameter.

ioat: convert ioat_probe to pcim/devm
The driver currently duplicates much of what these routines offer, so
just use the common code. For example ->irq_mode tracks what interrupt
mode was initialized, which duplicates the ->msix_enabled and
->msi_enabled handling in pcim_release.
This also adds a check to the return value of dma_async_device_register,
which can fail.

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).
