[PATCH RESEND 5/8] net: sunbmac: use platform_{get,set}_drvdata()

[Libo Chen <clbchenlibo.chen@huawei.com>]

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.
