Alexey Kardashevskiy c6e7958eb7 vfio/spapr: Allow fallback to SPAPR TCE IOMMU v1 ...

The vfio_iommu_spapr_tce driver advertises kernel's support for
v1 and v2 IOMMU support, however it is not always possible to use
the requested IOMMU type. For example, a pseries host platform does not
support dynamic DMA windows so v2 cannot initialize and QEMU fails to
start.

This adds a fallback to the v1 IOMMU if v2 cannot be used.

Fixes: 318f67ce1371 ("vfio: spapr: Add DMA memory preregistering (SPAPR IOMMU v2)")
