In theory there's no difference between one multi-segment transaction
and many single-segment transactions _in a single-master scenario_.

However, it is a plausible configuration to have multiple guests sharing
an I2C host device as if they were multiple master.

For this reason, I would prefer to have at least support for
transactions with 1 write and 1 read segment to the same address (see my
other message).
