AC97 configures some registers earlier to start a communication with CODECs, so this patch moves those register settings to the dai_probe() as well, along with other register configurations.
This patch breaks AC'97 CODEC probing.
Namely, the fsl_ssi DAI probe callback is only called after the AC'97 CODEC probe callback, so when you move SSI AC'97 startup to its DAI probe callback it won't be done yet when the CODEC is probed (and this requires a working AC'97 interface to successfully complete).
Hmm...What's the dependency here? Why is it required like this? I am okay to put everything to a separate fsl_ssi_hw_init() and move it back to the platform probe() though.
