topology2: Add SSP DAI class

Add SSP DAI class definition, SSP DAI objects can be
instantiated as:

Object.Dai.SSP."N" {
    direction		"duplex"
    dai_name		"NoCodec-0"
    id 			0
    quirks		"lbm_mode"
    sample_bits		24
    Object.hw_config."0" {
	    mclk_freq	24000000
	    bclk_freq	4800000
	    tdm_slot_width	25
    }
    Object.dai."playback" {
	    period_source_count	2
	    period_sink_count	0
    }
    Object.dai."capture" {
	    period_source_count	0
	    period_sink_count	2
    }
}
