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.

In case CONFIG_SECURE_BOOT is enabled we need to limit the SPL size to
avoid a possible HAB failure event:

RSN = HAB_INV_ADDRESS (0x22)
CTX = HAB_CTX_TARGET (0x33)
ENG = HAB_ENG_ANY (0x00)
As explained in Commit 23612534fe ("spl: imx6: Provide a SPL_SIZE_LIMIT

The ROM code is copying the image size defined in boot data to its
respective load address, in case we exceed the OCRAM free region a
HAB invalid address failure event is generated.

- CONFIG_SPL_FS_EXT4: u-boot-dtb.img is stored in raw sector via dd
command (at offset 69 kB)
- CONFIG_SPL_I2C_SUPPORT: I2C is not used during SPL
- CONFIG_SPL_OS_BOOT: no need to make Falcon mode supported
