commit 8780cf1142a59568a3aa77959cbd76b2edb6fd81
Author: Ajit Pandey <ajitp at codeaurora.org>

    ASoC: soc-core: defer card probe until all component is added to list
    
    DAI component probe is not called if it is not present
    in component list during sound card registration.
    Check if component is available in component list for
    platform and cpu dai before soundcard registration.
