register SSI_MODE is set when SSI works in TDM Extended or TDM (Ex-)Split mode, but it isn't reset after SSI stops. this will cause issue, if SSI starts to work in other modes which requie SSI_MODE to have different value.
This patch resets SSI_MODE register in .stop callback, when last stream calls .stop.
