Since there is some problematic i2c slave devices on some
platforms such as dkb (sometimes), it will drop down sda
and make i2c bus hang, at that time, it need to config
scl/sda into gpio to simulate "stop" sequence to recover
i2c bus, so add this interface.

Please note that the i2c core has a bus recovery infrastructure.
Search i2c.h for struct i2c_bus_recovery_info.
