arm64: dts: imx8mm-venice-*: add RTC aliases

Browse source 
Add aliases for the RTCs on the Gateworks Venice boards and on the imx8m
SoC. This ensures that the primary RTC is always the one on-board
provided by the Gateworks System Controller (GSC) which is battery
backed as opposed to the one in the IMX8M.
