Codrin Ciubotariu 87f0d9a518 ASoC: dmaengine: Restore NULL prepare_slave_config() callback

commit 660564fc9a upstream.

As pointed out by Sascha Hauer, this patch changes:
if (pmc->config && !pcm->config->prepare_slave_config)
        <do nothing>
to:
if (pmc->config && !pcm->config->prepare_slave_config)
        snd_dmaengine_pcm_prepare_slave_config()

This breaks the drivers that do not need a call to
dmaengine_slave_config(). Drivers that still need to call
snd_dmaengine_pcm_prepare_slave_config(), but have a NULL
pcm->config->prepare_slave_config should use
snd_dmaengine_pcm_prepare_slave_config() as their prepare_slave_config
callback.
