ASoC: soc-core: merge snd_soc_unregister_component() and snd_soc_unregister_component_by_driver()

We have below 2 functions, but these are very similar

(A)	snd_soc_unregister_component_by_driver()
(B)	snd_soc_unregister_component()

(A)	void snd_soc_unregister_component_by_driver(...)
	{
		...

(a)		mutex_lock(&client_mutex);
 ^ (X)		component = snd_soc_lookup_component_nolocked(dev, component_driver->name);
 |		if (!component)					   ^^^^^^^^^^^^^^^^^^^^^^
 |			goto out;
(b)
 |		snd_soc_del_component_unlocked(component);
 v
	out:
(c)		mutex_unlock(&client_mutex);
	}

(B)	void snd_soc_unregister_component_by_driver(...)
	{
(a)		mutex_lock(&client_mutex);
 ^		while (1) {
 | (X)			struct snd_soc_component *component = snd_soc_lookup_component_nolocked(dev, NULL);
 |												     ^^^^
(b)			if (!component)
 |				break;
 |
 |			snd_soc_del_component_unlocked(component);
 v		}
(c)		mutex_unlock(&client_mutex);
	}

Both are calling lock (a), find component and remove it (b), and
unlock (c). The big diff is whether use driver name for lookup() or
not (X).

Merge these into snd_soc_unregister_component_by_driver() (B), and
snd_soc_unregister_component_by_driver() (A) can be macro.
