board: stm32mp1: move set_dfu_alt_info in st common directory
Move the stm32mp1 common code set_dfu_alt_info() in common directory, this patch reduce the maintenance effort on this generic part (not board dependent). Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com> Reviewed-by: Patrice Chotard <patrice.chotard@st.com>
