* Catch the slave interrupts and send appropriate i2c_slave_events to the backend.
Note that most hardware supports being master _and_ slave on the same bus. So,
if you extend a bus driver, please make sure that the driver supports that as
well. In almost all cases, slave support does not need to disable the master
functionality.
Check the i2c-rcar driver as an example.
