env_sf: support embedded environments
If both CONFIG_ENV_SECT_SIZE and CONFIG_ENV_SIZE are defined, and the sect size is larger than the env size, then it means the env is embedded in a block. So we have to save/restore the part of the sector which is not the environment. Previously, saving the environment in SPI flash in this setup would probably brick the board as the rest of the sector tends to contain actual U-Boot data/code.
