stack_setup is modified to initialize the stack on the correct address in DRAM accroding to the typical memory configuration described in README and the related CONFIG_* macro definitions. This makes macro CONFIG_MEMORY_UPPER_CODE no longer necessry. This was introduced and used only by this board for some unclear reason. The definition of this macro is removed because it's not referenced elsewhere.
