Eric Auger 9e54dee71f hw/arm/smmu-common: Manage IOTLB block entries 
At the moment each entry in the IOTLB corresponds to a page sized
mapping (4K, 16K or 64K), even if the page belongs to a mapped
block. In case of block mapping this unefficiently consumes IOTLB
entries.

Change the value of the entry so that it reflects the actual
mapping it belongs to (block or page start address and size).

Also the level/tg of the entry is encoded in the key. In subsequent
patches we will enable range invalidation. This latter is able
to provide the level/tg of the entry.

Encoding the level/tg directly in the key will allow to invalidate
using g_hash_table_remove() when num_pages equals to 1.
