sunxi: Add limit with the MMC environment

Browse Source 
The MMC environment offset is getting very close to the end of the U-Boot
binary now. Since we want to make sure this will not overflow, add a size
limit in the board for arm64. arm32 has already that limit enforced in our
custom image generation.
