i2c: Remove i2c_algorithm.algo_control()
This removes:
- An effectively unused hook: i2c_algorithm.algo_control.
- The i2c_control() call, used only by i2c-dev to call that
unused hook or set two barely supported adapter params.
(That param setting moves into i2c-dev.c ... still iffy
due to lack of locking, but no other changes.)
As shown by diffstat, this is a net code shrink. It also reduces the
complexity of the I2C adapter and /dev interfaces.
