This patch adds a configuration option to force the IOVA mode to
physical address (PA). There exists virtual devices that are not
directly attached to the PCI bus, and therefore the auto detection
of the IOVA mode based on probing the PCI bus and IOMMU configuration
may not report the required addressing mode. Having the configuration
option permits the mode to be explicitly configured in this scenario.

Defining this at compile-time seems like an overkill. Wouldn't it be
better to just add an EAL command-line option to force IOVA mode to a
particular value?
