The i.MX8M Nano can boot over USB using the boot ROM instead of adding extra code to SPL to support USB drivers, etc. However, when booting from USB, the environment doesnt' know where to load and causes a hang. Fix this hang by supporting CONFIG_ENV_IS_NOWHERE=y. It only falls back to this condition when booting from USB, so it does not impact MMC booting.
