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

Add support for fe_dai objects:

For ex:

Object.PCM.pcm."0" {
	name	"Port0"
	direction	"duplex"
	Object.Base.fe_dai."Port 0" {}
}

will be converted to update the SectionPCM as follows:

SectionPCM {
        Port0 {
                id 0
                dai {
                        'Port 0' {
				id 0
			}
                }
}
