rtc: update to class device removal patches
Fix a goof in the revised classdev support for RTCs: make sure the /dev node info is ready before the device is registered, not after. Otherwise the /sys/class/rtc/rtcN/dev attribute won't be created and then udev won't have the information it needs to create the /dev/rtcN node.
