On ppc64, without huge pages, pa would be the default but fails like:
  EAL: Cannot use IOVA as 'PA' since physical addresses are not available

On a normal system setup we'd expect an admin to set up huge pages
and for the unlikely case that they do not do that set iova=va
themselve. But the testing infrastructure does not have this conscious
admin that will do that, so fix test execution that by adjusting the
tests arguments accordingly if the conditions are met.
