ASoC: codecs: fix widget name comparisons

Browse source 
Merge series from Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>:

Some codec drivers compare widget names with strcmp, ignoring the component
name prefix.  If prefix is used, the comparisons start failing.
Add a helper to fix the issue.
