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.

The ifpga and skeleton rawdev drivers included "rawdev" in their directory
names, which was superfluous given that they were in the drivers/raw
directory. Shorten the names via this patch.
For meson builds, this will rename the final library .so/.a files
produced, but those will be renamed again later via a patch to
standardize rawdev names.

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.
