Subject: [PATCH] ASoC: fsl: set correct platform drvdata in pcm030_fabric_probe()

From: Wei Yongjun <yongjun_wei@...ndmicro.com.cn>

platform_set_drvdata(op, pdata) in pcm030_fabric_probe()
will be overwrited when calling snd_soc_register_card(card),
but cm030_fabric_remove() use drvdata as a type of struct
pcm030_audio_data, so we should move platform_set_drvdata()
below snd_soc_register_card() call.
