[PATCH v5 32/37] MIPS: JZ4740: only detect RAM size if not specified in DT

Allow a devicetree to specify the memory present in the system rather than probing it from the memory controller. This both saves the probing for systems where the amount of memory is fixed, and will simplify the bringup of later Ingenic SoCs where the memory controller register layout differs.
