ARM: dts: aspeed-romulus: Add I2C devices

Enable the buses that are in use and the devices that are attached.
Currently that is just the battery backed RTC.

Some of these buses are for hotplugged cards, such as PCIe cards. Others
do not yet have upstream drivers, so there are no devices attached.
