hw/arm/smmu: Introduce SMMUTLBEntry for PTW and IOTLB value
Introduce a specialized SMMUTLBEntry to store the result of
the PTW and cache in the IOTLB. This structure extends the
generic IOMMUTLBEntry struct with the level of the entry and
the granule size.
Those latter will be useful when implementing range invalidation.
