Frieder Schrempf 6e91c06a73 arm64: dts: imx8mm-kontron: Add RTC aliases 
Add aliases for the RTCs on the board and on the SoC. This ensures that
the primary RTC is always the one on the board that has a buffered supply
and maximum accuracy.

This is a direct port of the pending commit from linux-next.
