It is bad practice to include common.h in other header files since it can bring in any number of superfluous definitions. It implies that some C files don't include it and thus may be missing CONFIG options that are set up by that file. The C files should include these themselves. Update some header files in arch/arm to drop this. Signed-off-by: Simon Glass <sjg@chromium.org>
