If adding size to 8192/8195 is very difficult, at least we can add a Kconfig to identify if the SoC supports sdram, and early return in add_mem_chip_info.

Or, we may even consider extending the early_init / persistent_data thing, to make dram_size part of it, so every platforms can update the  DRAM size in the future.
