ASoC: SOF: Intel: HDA: add hw params callback for SSP DAIs
Currently SSP DAIs don't have hw params callback function as there wasn't anything to setup after initial topology loading. After enabling multiple DAI configs the current config can be sent in the callback. This patch changes the way SSP config ipc is sent to the dsp. Before it was only sent once in topology loading, but now it will be additionally sent always when stream is opened. Mechanism is similar as with HDA DAIs.
