[U-Boot] [PATCH v5] pico-imx7d: Increase the CONFIG_ENV_OFFSET size

U-Boot binary has grown in such a way that it goes beyond the reserved
area for the environment variables.
Running "saveenv" 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 again in
the future, use CONFIG_BOARD_SIZE_LIMIT, which will detect the overlap
in build-time.
CONFIG_BOARD_SIZE_LIMIT is CONFIG_ENV_OFFSET - 69 kB, as u-boot.img
is flashed into the 69 kB offset.

Hi Stefano,
This one depends on Wolfgang's v2 patch:
