Subject: [PATCH v3 3/5] i2c: recovery: change input parameter to i2c_adapter for prepare/unprepare_recovery

This patch changes type of input parameter for .prepare/unprepare_recovery()
callbacks from struct i2c_bus_recovery_info * to struct i2c_adapter *.
This allows to simplify implementation of these callbacks and avoid
type conversations from i2c_bus_recovery_info to i2c_adapter.
The i2c_bus_recovery_info can be simply retrieved from struct i2c_adapter
which contains pointer on it.
