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.
