sparc64: Check for RTC class device in update_persistent_clock().
As we convert the various by-hand sparc64 RTC drivers to use the generic RTC framework and drivers, we need to keep the NTP set_rtc_mmss() support via update_persistent_clock() working. In the end, after all the RTC device cases are converted, this local set_rtc_mmss() function will be deleted. Signed-off-by: David S. Miller <davem@davemloft.net>
