Maybe we can just drop the comment? The value we write is pretty self-explaining.

Match the wording of this driver wrt. the newest I2C v7, SMBus 3.2, I3C specifications and replace "master/slave" with more appropriate terms. They are also more specific because we distinguish now between a remote entity ("client") and a local one ("target").
