PENDING: arm64: dts: ti: k3-j721s2-main: Add DDR nodes for J721S2

Browse Source 
Add DT nodes for the 2 DDR controllers on the J721S2 device. These define
the memory controller with its register regions, interrupts, power
domains, and clock requirements.

This allows for DDR controller temperature monitoring.
