Add architecture-specific global data
We plan to move architecture-specific data into a separate structure so that we can make the rest of it common. As a first step, create struct arch_global_data to hold these fields. Initially it is empty. This patch applies to all archs at once. I can split it if this is really a pain. Signed-off-by: Simon Glass <sjg@chromium.org>
