According to PCIe specification, a 64-bit MMIO BAR should be
naturally aligned. In addition to being more compliant with
the specification, natural aligned BARs are mapped with
the largest possible page size by the host iommu driver, which
should speed up boot time and reduce IOTLB thrashing for virtual
machines with VFIO devices.
