Move DECLARE_GLOBAL_DATA_PTR to file scope
It can be optimised out by the compiler otherwise resulting in obscure errors like a board not booting. This has been documented in README since 2006 when these were first fixed up for GCC 4.x. Signed-off-by: John Rigby <john.rigby@linaro.org> Fix some additional places. Signed-off-by: Wolfgang Denk <wd@denx.de> Acked-By: Albert ARIBAUD <albert.aribaud@free.fr>
