arm64: dts: imx8m: Add ddr controller nodes
This is used by the imx-ddrc devfreq driver to implement dynamic
frequency scaling of DRAM.
Support for proactive scaling via interconnect will come later. The
high-performance bus masters which need that (display, vpu, gpu) are
mostly not yet enabled in upstream anyway.
