clk: sunxi-ng: Fix H6 RTC clock definition

While RTC clock was added in H616 ccu_common list, it was not in H6
list. That caused invalid pointer dereference like this:

Unable to handle kernel NULL pointer dereference at virtual address 000000000000020c

Fix that by adding rtc clock to H6 ccu_common list too.
