David Hildenbrand c726aa6941 memory-device: Add get_min_alignment() callback
Add a callback that can be used to express additional alignment
requirements (exceeding the ones from the memory region).

Will be used by virtio-mem to express special alignment requirements due
to manually configured, big block sizes (e.g., 1GB with an ordinary
memory-backend-ram). This avoids failing later when realizing, because
auto-detection wasn't able to assign a properly aligned address.
