65bcddfc66 raw/ioat: build only if dmadev not present
Only build the rawdev IDXD/IOAT drivers if the dmadev drivers are not
present.

This change requires the dependencies to be reordered in
drivers/meson.build so that rawdev can use the "RTE_DMA_* build macros to
check for the presence of the equivalent dmadev driver.

A note is also added to the documentation to inform users of this change.

b7aaf417f9 raw/ioat: add bus driver for device scanning automatically

devices automatically using a bus-type driver. This bus does not need to
worry about registering device drivers, rather it can initialize the
devices directly on probe.

Add in the basic probe/remove skeleton code for DSA devices which are bound
directly to vfio or uio driver. The kernel module for supporting these uses
the "idxd" name, so that name is used as function and file prefix to avoid
conflict with existing "ioat" prefixed functions.

Since we are adding new files to the driver and there will be common
definitions shared between the various files, we create a new internal
header file ioat_private.h to hold common macros and function prototypes.

f55d185540 raw/ioat: add separate API for fence call
Rather than having the fence signalled via a flag on a descriptor - which
requires reading the docs to find out whether the flag needs to go on the
last descriptor before, or the first descriptor after the fence - we can
instead add a separate fence API call. This becomes unambiguous to use,
since the fence call explicitly comes between two other enqueue calls. It
also allows more freedom of implementation in the driver code.

979e29ddbb raw/ioat: rename functions to be operation-agnostic
Since the hardware supported by the ioat driver is capable of operations
other than just copies, we can rename the doorbell and completion-return
functions to not have "copies" in their names. These functions are not
copy-specific, and so would apply for other operations which may be added
later to the driver.

Also add a suitable warning using deprecation attribute for any code using
the old functions names.

Currently with the rawdev API there is no way to check that the structure
passed in via the dev_private pointer in the structure passed to configure
API is of the correct type - it's just checked that it is non-NULL. Adding
in the length of the expected structure provides a measure of typechecking,
and can also be used for ABI compatibility in future, since ABI changes
involving structs almost always involve a change in size.
