[U-Boot] [PATCH] Env. vars fix for lite5200

I still have a few older lite5200 boards around and when I recently tried to upgrade U-Boot I ran into weird problems where "saveenv" would fry the bootloader. Attached is a fix. It seems that somewhere along the way the image size grew larger than 256K and the address for the env vars overlapped with the code.

P.S.: Apologies for not putting the patch inline, the email provider I use has a brain-dead policy of enforcing line-wraps on text emails :/
