s390: remove driver_data direct access of struct device

In the near future, the driver core is going to not allow direct access
to the driver_data pointer in struct device.  Instead, the functions
dev_get_drvdata() and dev_set_drvdata() should be used.  These functions
have been around since the beginning, so are backwards compatible with
all older kernel versions.

Thanks to Sebastian Ott <sebott@linux.vnet.ibm.com> for fixing a few
typos in my original version of this patch.
