ASoC: soc-core.c: setup rtd->pmdown_time at soc_new_pcm_runtime()

Browse Source 
Almost all default rtd->xxx are setup at soc_new_pcm_runtime()
which is sub-function of snd_soc_add_pcm_runtime() (A).
But "rtd->pmdown_time" is setup at soc_init_pcm_runtime() (B).
It is very random timing setup. This patch setup it at (A),
same as other rtd->xxx.

	static int snd_soc_bind_card(...)
	{
		...
		for_each_card_prelinks(...) {
(A)			ret = snd_soc_add_pcm_runtime(...);
			...
		}
		...
		for_each_card_rtds(...) {
(B)			ret = soc_init_pcm_runtime(...);
			...
		}
		...
	}

One note is that current topology/intel are directly calling
snd_soc_add_pcm_runtime() (A) without calling soc_init_pcm_runtime() (B).
This means, its "rtd->pmdown_time settings" was 0, but will have default
value by this patch.

"rtd->pmdown_time settings" will be used at
snd_soc_runtime_ignore_pmdown_time(). This patch adds
"ignore_pmdown_time" to these driver to keep compatibility.

	bool snd_soc_runtime_ignore_pmdown_time(...)
	{
		...
=>		if (!rtd->pmdown_time || rtd->dai_link->ignore_pmdown_time)
			return true;
		...
	}
