[PATCH] arm64: dts: imx8mm-venice-*: add RTC aliases

From: Tim Harvey
Date: Mon Sep 09 2024 - 18:15:21 EST

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.
