ASoC: Fixes for v4.4 Quite a large batch of fixes have come in since the merge window, mainly driver specific ones but there's a couple of core ones: - A fix for DAPM resume on active streams to ensure everything ends up cleanly in the right state. - Reset the DAPM cache when freeing widgets to fix a crash on driver remove and reload. The PM functions for nau8825 are new code which fix crashes on resume.
