ASoC: partial match the sdca codec name

Merge series from Bard Liao <yung-chuan.liao@linux.intel.com>:

Currently, we set a predefined codec component name in a DAI link. But
the codec name may contain an index which is not fixed. This series
suggest using partial match the codec name to fix the issue.
