Fore example, the frontend may kick the sequence "write read read ..."

The segments can be aggregated into "i2c_msg list" and sent to the
hardware at a time by the backend.
The host native drivers will finally send these segments using the
methods they support.
If so, the spec needs to specify what the backend must/should/may
aggregate into a single host-side transaction.
What my proposal does is essentially saying that the backend MUST
aggregate a write and a read segment into a single transaction if it is
sent with a single virtio-i2c request.
