Subject: [PATCH v2 0/5] ASoC: core: add support to card re-bind using component framework

During discussion regarding card re-binding when components unregister
and register back at https://lkml.org/lkml/2018/7/9/785 it was suggested
that component framework can be added into core to provide this feature.

With this new changes the card will re-bind once the dependent component
re-registers after unregistering. This works based on the match done
from component name using component framework.

I have tested this patch with qdsp start-stop and module-load-unload usecase
for more than 10000 times in loop on Qcom platforms.

Thanks,
srini

Changes since v1:
 - Added new flag to enable/disable auto bind at card level, It is useful
  if machine driver/module is really removed/unloaded. Also to help cleanup
  the master component. Without this we will endup with a memory leak if the
  machine driver and memory associated with card are removed.
 - removed unregister from unbind callback.
 - updated match function as suggested by Vinod.
 - Added qdsp6 cleanup patches to this series.
