stm32mp1: dynamically build DFU_ALT_INFO
This patch reduces the stm32mp1 environment size and builds dynamically the DFU board configuration with gpt and mtd partitions and information from defconfig (CONFIG_DFU_ALT_RAM0). Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com> Reviewed-by: Patrice Chotard <patrice.chotard@st.com>
