env: Remove all dependencies for SYS_REDUNDAND_ENVIRONMENT
CONFIG_SYS_REDUNDAND_ENVIRONMENT is changing in env_internal.h how u-boot
works with variables. struct environment_s has one byte flags property
which also affects ENV_SIZE macro.
I have reached the case where CONFIG_ENV_IS_NOWHERE is default setup
but custom scripts can be designed in a way that u-boot is asked to
import/export variables from/to file which can be in certain format.
That's why also for this configuration make sense to enable
CONFIG_SYS_REDUNDAND_ENVIRONMENT because it depends on environment file
format.
The patch is removing dependency on this configuration to support selecting
environment file format without any specific dependency where variables are
stored.
