[PATCH 2/4] fdtdec: Update fdtdec_setup_mem_size_base_fdt() to call fdtdec_get_mem_size_base()

[Bin Meng <bmeng.cn@gmail.com>]

From: Bin Meng <bin.meng@windriver.com>

The only difference betwen fdtdec_setup_mem_size_base_fdt() and
fdtdec_get_mem_size_base() is that the former does the assignment
to gd->ram_size and gd->ram_base.

Simplify the codes to call fdtdec_get_mem_size_base() directly.
