davinci: da8xx/omap-l1x: add platform device for davinci-pcm-audio

After the multi-component commit f0fba2ad (ASoC: multi-component - ASoC Multi-Component Support) for ASoC, we need to register the platform device for davinci-pcm-audio.

This patch and patch at [1] are required for audio to work on DA850/OMAP-L138.

Since v1, removed davinci_init_pcm() function and called platform_device_register() from within da8xx_register_mcasp().
