Add slave mode functionality for the Aspeed I2C controller. This is
implemented by creating an Aspeed I2C Slave device that attaches to the
bus.
This i2c slave device only implements the asynchronous version of
i2c_send() and the event callback.

Eventually split this hunk into a separate patch to have better readability.
