Subject: [PATCH 03/12] ASoC: Intel: Remove unnecessary function call

First of all,the address of pdev->dev is assigned to card->dev, when
calling snd_soc_register_card,the function dev_set_drvdata(card->dev, card)
copies the value the variable card to card->dev->driver_data.After
that,the function platform_set_drvdata does the same copy operation,
so i think that the latter copy operation can be removed.
