Subject: [PATCH RESEND 3/8] net: fec_mpc52xx_phy: use platform_{get,set}_drvdata()

From: Libo Chen <[email-masked]>
Date: Wed, 14 Aug 2013 11:39:36 +0800

We can use the wrapper functions platform_{get,set}_drvdata() instead of
dev_{get,set}_drvdata() with &of->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.
