Move the population of the codec_conf array from endpoint parsing
time to link creation time. This is slightly cleaner as the
population is done whilst the DAI links are also being populated,
putting all population together. However, primarily this facilitates
allowing additional non-SoundWire devices to be easily added into
the array in future feature additions.
