fvp: Remove call to bl2_get_ns_mem_layout() function
On FVP platforms, for now it is assumed that the normal-world bootloader is already sitting in its final memory location. Therefore, BL2 doesn't need to load it and so it doesn't need to know the extents of the non-trusted DRAM. Change-Id: I33177ab43ca242edc8958f2fa8d994e7cf3e0843
