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. The first step renames the members of struct
i2c_algorithm. Once all in-tree users are converted, the anonymous union
will go away again. All this work will also pave the way for finally
seperating the monolithic header into more fine-grained headers like
"i2c/clients.h" etc.
