i2c: reword i2c_algorithm in drivers according to newest specificationi2c/master_to_host

Match the wording in i2c_algorithm in I2C drivers wrt. the newest I2C
v7, SMBus 3.2, I3C specifications and replace "master/slave" with more
appropriate terms. For some drivers, this means no more conversions are
needed. For the others more works needs to be done but this will be
performed incrementally along with API changes/improvements. All these
changes here are simple search/replace results.
