ASoC: audio-graph-card2.c: remove pre-alloced Codec2Codec space

Browse source 
Because Codec2Codec settings becomes optional, we don't need to keep
its parameter space when init time. This patch removes its default
memory allocation from simple-card-utils.c, and allocate it at
audio-graph-card2 ondemand.
