RTCs are using sequence number defined in aliases node. Date command with DM_RTC enabled is looking for the first RTC with index 0. But when RTC_EMULATION is enabled it gets likely most of the time index 0 even when system has rtc0 device via aliases node and gets sequence number 0. That's why extend the code to look for sequence 0 number first. If this fails continue to use existing device with index 0.
