lib: fdt: Split fdtdec_setup_memory_banksize()
Split fdtdec_setup_memory_banksize() into fdtdec_setup_memory_banksize_fdt(), which allows the caller to pass custom blob into the function and the original fdtdec_setup_memory_banksize(), which uses the gd->fdt_blob. This is useful when configuring the DRAM properties from a FDT blob fragment passed in by the firmware.
