We should not use typedefs in U-Boot. They cannot be used as forward declarations which means that header files must include the full header to access them. Drop the typedef and rename the struct to remove the _s suffix which is now not useful. This requires quite a few header-file additions. Signed-off-by: Simon Glass <sjg@chromium.org>
