ASoC: fsl: pcm030-audio-fabric use snd_soc_register_card
Convert pcm030-audio-fabric to use the new snd_soc_register_card api
instead of the older method of registering a separate platform device.
Create the dai_link to the mpc5200_psc_ac97 platform using the device tree.
Convert the pcm030-audio-fabric driver to a platform-driver and add a
remove function.
