Subject: [PATCH RESEND 8/8] net: davinci_mdio: use platform_{get,set}_drvdata()


We can use the wrapper functions platform_{get,set}_drvdata() instead of
dev_{get,set}_drvdata() with &pdev->dev, it is convenient for user.

Also, unnecessary dev_set_drvdata() is removed, because the driver core
clears the driver data to NULL after device_release or on probe failure.
