[PATCH] mx51evk: Fix U-Boot corruption after saving the environment

[sbabic at denx.de]

> U-Boot binary has grown in such a way that it goes beyond the reserved
> area for the environment variables.
> Running "saveenv" followed by a "reset" causes U-Boot to hang because
> of this overlap.
> Fix this problem by increasing the CONFIG_ENV_OFFSET size.
> Also, in order to prevent this same problem to happen in the future,
> use CONFIG_BOARD_SIZE_LIMIT, which will detect the overlap in build-time.
> CONFIG_BOARD_SIZE_LIMIT does not accept math expressions, so declare
> CONFIG_ENV_OFFSET with its direct value instead.
