Modern C compilers warn about unannotated switch/case fallthrough code, and require either a comment with some magic words, or an explicit compiler attribute. Since some TF-A static analysis CI check suggests having a "fallthrough;" statement instead of a comment, introduce a macro that implements that statement, and emits the proper compiler attribute.
