hw/arm/smmuv3: Enforce invalidation on a power of two range
As of today, the driver can invalidate a number of pages that is
not a power of 2. However IOTLB unmap notifications and internal
IOTLB invalidations work with masks leading to erroneous
invalidations.
In case the range is not a power of 2, split invalidations into
power of 2 invalidations.
When looking for a single page entry in the vSMMU internal IOTLB,
let's make sure that if the entry is not found using a
g_hash_table_remove() we iterate over all the entries to find a
potential range that overlaps it.
