Please split the model into 2 models:

- One generic model for Synopsys DesignWare SSI controller
- One K230 specific wrapper model on top of the Synopsys DesignWare
SSI controller [optional, if the generic model is enough to make the
k230 software happy]

This way we can reuse the Synopsys DesignWare SSI controller model by
other machines in the future.
