boards: st: nucleo_u5a5zj_q: Import TF-M code
Add the TF-M S image code dedicated to the board, which uses an Out-Of-Tree approach. This can be used as example to customers interested in this technology and don't have an initial idea how to do it. This will avoid that customers will try the easy script copy over TF-M folder patch. Signed-off-by: BUDKE Gerson Fernando <gerson.budke@leica-geosystems.com>
