ASoC: simple-card-utils.c: care Codec2Codec vs DPCM:BE

Current asoc_simple_init_for_codec2codec() adds default Codec2Codec
settings if rtd was Codec only.
But DPCM:BE also judged as Codec only, because dummy-DAI doesn't have
"endianness" (which is key parameter to judge as Codec).

This patch ignores setup Codec2Codec settings if it was DPCM:BE case.
