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.

Some of these defines may be useful outside of dma.c and the header is
private so there are no namespace pollution concerns.

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).
