> IOMMU capabilities won't change and must be checked even if no PCI device
> seem to be supported yet when EAL initialised.
> 
> This is to accommodate with SPDK that registers its drivers after
> rte_eal_init(), especially on PPC platform where the IOMMU does not
> support VA.
> 
> Fixes: 703458e19c16 ("bus/pci: consider only usable devices for IOVA mode")
