ASoC: omap-hdmi-audio: Add platform device for OMAP HDMI audio support
The platform device should only be registered from OMAPDSS HDMI driver. The platform driver registers and unregisters all ASoC components needed for OMAP HDMI audio. The hdmi audio driver implements cpu-dai component using the callbacks provided by OMAPDSS and registers the component under DSS HDMI device. Omap-pcm is registered for platform component also under DSS HDMI device. Dummy codec is used as as codec component. The hdmi audio driver implements also the card and registers it under its own platform device.
