ASoC: ux500: Remove unnecessary function call

First of all,the address of pdev->dev is assigned to mop500_card.dev,
then the function platform_set_drvdata copies the value the variable
card to pdev->dev.driver_data,but when calling snd_soc_register_card,
the function dev_set_drvdata(card->dev, card) will also do the same
copy operation,so i think that the former copy operation can be removed.
