Driver core: add device symlink back to sysfs
This moves the device symlink back to sysfs even if
CONFIG_SYSFS_DEPRECATED is enabled as too many userspace programs (well,
HAL), still rely on this link to be present.
I will rework the ability for sysfs to change layouts like this in the
future, but for now, this patch should fix people's network connections.
