[RFC PATCH] ASoC: Samsung: Register the audio platform device

[Padmavathi Venna]

Audio platform device is not a hardware peripherial.
So this device can't be added in the dt devices list.
So expanded the module_platform_driver and registered
this device using "platform_device_register_simple".

Also added the soc-core pm ops structure in the audio
platform driver.
