At the moment we have each SoC's memory map defined in its own cpu.h, which is included in include/configs/sunxi_common.h. This will be a problem with the introduction of Allwinner RISC-V support.
Remove the inclusion of that header file from the common config header, instead move the required serial base addresses (for the SPL) into a separate header file. Then include the original cpu.h file only where we really need it, which is only under arch/arm now.
This disentangles the architecture specific header files from the generic code.
