arm: dts: k3-am64-main: Reserve OCMRAM for DMSC-lite and secure proxy communication The final 128KB in SRAM is reserved by default for DMSC-lite code and secure proxy communication buffer. The memory region used for DMSC-lite code can be optionally freed up by secure firmware API[1]. However, the buffer for secure proxy communication is not configurable. This default hardware configuration is unique for AM64. Therefore, indicate the area reserved for DMSC-lite code and secure proxy communication buffer in the oc_sram device tree node.
