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 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.

Add the initial support for the pico-imx6 variants.

DDR initialization is based on the TechNexion's U-Boot code.

CONFIG_SPL_OS_BOOT=y needs to be passed in the defconfig in order to use Falcon mode.
