[PATCH 13/15] ASoC: remove snd_soc_dai_link_set_capabilities()

[Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>]

snd_soc_dai_link_set_capabilities() checks all CPU/Codec DAI (Y)(Z)
for Playback/Capture (X) and checks its validation (A), and setup
dpcm_playback/capture flags (a).

	void snd_soc_dai_link_set_capabilities(...)
	{
		...
(X)		for_each_pcm_streams(direction) {
			...
(Y)			for_each_link_cpus(dai_link, i, cpu) {
				...
(A)				if (... snd_soc_dai_stream_valid(...)) {
					...
				}
			}
(Z)			for_each_link_codecs(dai_link, i, codec) {
				...
(A)				if (... snd_soc_dai_stream_valid(...)) {
					...
				}
			}
			...
		}

(a)		dai_link->dpcm_playback = supported[...];
(a)		dai_link->dpcm_capture  = supported[...];
	}

This validation check will be automatically done on new
soc_get_playback_capture(). snd_soc_dai_link_set_capabilities() is no
longer needed. Let's remove it.
