Previously, the ASoC 'platform' (PCM/DMA) object was instantiated via a platform_device. This didn't represent the hardware well, since there was no separate hardware associated with this platform_device; it was a virtual device with sole purpose to call snd_soc_register_platform(). This change removes the platform_device completely. Each Samsung DAI now registers the ASoC 'platform' itself. Machine drivers are adjusted for the new 'platform' name.
