virtio-mem: allow to force Big Block Mode (BBM) and set the big block size
Let's allow to force BBM, even if subblocks would be possible. Take care
of properly calculating the first big block id, because the start
address might no longer be aligned to the big block size.
Also, allow to manually configure the size of Big Blocks.
