lib: fdt: Split fdtdec_setup_mem_size_base()

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