The imx8mn_beacon board does not use the same memory map as the reference design from NXP or other imx8mn boards. As such, memory is more limited in SPL. Moving SPL_BSS_START_ADDR and SPL_STACK to default locations increases the amount of available meory for the SPL stack. Doing this allows the board to no longer define CONFIG_MALLOC_F_ADDR. Since SYS_LOAD_ADDR also does not align with other boards, move it too.
