topology: pre-process-dai: add support for hwcfg objects

Add supprt for hwcfg objects:
For ex:
Object.Base.hw_config."SSP0 hw_config 0" {
		id		0
		mclk_freq	24000000
		bclk_freq	4800000
		tdm_slot_width	25
	}

would get converted to:

SectionHWConfig {
        'SSP0 hw_config 0' {
                id 0
                format I2S
                bclk codec_consumer
                bclk_freq 4800000
                fsync codec_consumer
                fsync_freq 48000
                mclk codec_mclk_in
                mclk_freq 24000000
                tdm_slots 2
                tdm_slot_width 25
                tx_slots 3
                rx_slots 3
        }
}

and the corresponding SectionBE will be updated with the hwcfgs reference as:

	hw_configs [
		'SSP0 hw_config 0'
        ]
