[U-Boot] [PATCH] S3C6400/SMDK6400: fix stack_setup in start.S

["Seunghyeon Rhee (이승현)"]

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.
