When running the ioat_rawdev_autotest, the ring size was initially required
to be 0. This prevented the test being run multiple times, as the ring size
is modified to a non-zero value when running the first test.
A global variable is now used to track the expected ring size, and is used
in the initial value check. This enables the test to be run more than
once.

The ioat rawdev was initially started during the test, however was never
stopped. This would cause issues when running the test again, as the device
cannot be configured when in a running state.
The device is now stopped after the test has completed, or if the test is
terminated due to error.

The driver names for rawdevs were both different in make and meson builds
and were non-standard in the make version in that some included "rawdev" in
the name while others didn't.
Therefore, for global consistency of naming, we can use "rte_rawdev" rather
than "rte_pmd" for the prefix for the libraries. While most other driver
categories use "rte_pmd" as a prefix, there is precedent for this in the
mempool drivers use "rte_mempool" as a prefix.

Some builds with clang report an error because '<>' rather than '""' were
used for including the ioat spec header file.
Target: x86_64-native-bsdapp-clang
error: 'rte_ioat_spec.h' file not found with <angled> include; use "quotes" instead
#include <rte_ioat_spec.h>
^~~~~~~~~~~~~~~~~
"rte_ioat_spec.h"
1 error generated.
Since this file should always be in the same directory as the main header,
we can safely change the include line to fix this error.

The incriminated commit broke the use of RTE_PCI_DRV_IOVA_AS_VA which
was intended to mean "driver only supports VA" but had been understood
as "driver supports both PA and VA" by most net drivers and used to let
dpdk processes to run as non root (which do not have access to physical
addresses on recent kernels).
The check on physical addresses actually closed the gap for those
drivers. We don't need to mark them with RTE_PCI_DRV_IOVA_AS_VA and this
flag can retain its intended meaning.
Document explicitly its meaning.
We can check that a driver requirement wrt to IOVA mode is fulfilled
before trying to probe a device.
Finally, document the heuristic used to select the IOVA mode and hope
that we won't break it again.

When using _mm_set_epi64() rather than _mm_set_epi64x() intrinsic, ICC
tries to use the x87 floating point registers, leading to warnings about
not properly clearing value when switching between x87 and SSE/AVX modes.
error #13203: No EMMS instruction before call to function
Fix this by using the set64x() intrinsic.
