ASoC: mxs: mxs-pcm does not need to be a plaform_driver

Browse Source 
Same as the commit 518de86 (ASoC: tegra: register 'platform' from DAIs,
get rid of pdev), it makes mxs-pcm not a platform_driver but helper to
register "platform", so that the platform_device for mxs-pcm can be
saved completely.
