Current soc-dapm / soc-core are using a long way round to call
.seq_notifier.

	if (driver->seq_notifier)
		dapm->seq_notifier = ...;
	...
	if (dapm->seq_notifier)
		ret = dapm->seq_notifier(...);

We can directly call it via driver->seq_notifier.
One note here is that both Card and Component have dapm,
but, Card's dapm doesn't have dapm->component.
We need to check it.

This patch moves snd_soc_component_seq_notifier() to soc-component.c,
and updates parameters.
dapm->seq_notifier is no longer needed
