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").

Okay, we need to begin somewhere...
Start changing the wording of the I2C main header wrt. the newest I2C
v7, SMBus 3.2, I3C specifications and replace "master/slave" with more
appropriate terms. This first step renames the members of struct
i2c_algorithm. Once all in-tree users are converted, the
