This converts the following to Kconfig: CONFIG_SYS_MONITOR_LEN To do this, we set a default of 0 for everyone because there are a number of cases where we define CONFIG_SYS_MONITOR_LEN but the only impact is that we set TOTAL_MALLOC_LEN to be CONFIG_SYS_MALLOC_LEN + CONFIG_ENV_SIZE, so we must continue to allow all boards to set this value. Update the SPL code to use 200 KB as the default raw U-Boot size directly, if we don't have a real CONFIG_SYS_MONITOR_LEN value.
