Subject: [PATCH] ASoC: soc-core: self contained soc_unbind_aux_dev()
Git-commit: e8fbd2505242467044ec51bf57c642a50ed28a14
Patch-mainline: v5.4-rc1
References: jsc#SLE-16518

Current soc_unbind_aux_dev() implementation is very half,
thus it is very unreadable.

	for_each_comp_order(order) {
		for_each_card_auxs_safe(card, comp, _comp) {

(1)			if (comp->driver->remove_order == order) {
				...
=>				soc_unbind_aux_dev(comp);
			}
	}

soc_unbind_aux_dev() itself is not related to remove_order (1).
And, it is called from soc_remove_aux_devices(), even though
its paired function soc_bind_aux_dev() is called from
snd_soc_instantiate_card().
It is very unbalance, and very difficult to understand.

This patch do
1) update soc_bind_aux_dev() to self contained
2) call it from soc_cleanup_card_resources() to make up balance
