ASoC: dapm: Reorder the bias update sequence
The new sequence ensure that dapm_pre_sequence_async work on
the card before all codecs and dapm_post_sequence_async work
on the card after all codecs.
So the machine driver could utilize the determinate sequence
to do the gloabl setup and teardown in the right place.
