ASoC: fsl-asoc-card: Dynamically allocate memory for snd_soc_dai_link_components

Browse Source 
The static snd_soc_dai_link_components cause conflict for multiple
instances of this generic driver. For example, when there is
wm8962 and SPDIF case enabled together, the contaminated
snd_soc_dai_link_components will cause another device probe fail.
