We can just double CONFIG_ENV_ADDR for Flex-OneNAND, so
CONFIG_ENV_ADDR_FLEX is not needed.
Otherwise, we can just set env_addr to 1 block size as bootloader
is always limited to block 0.

I don't get alternative than to use CONFIG_ENV_SIZE_FLEX to store size 
of environment variables
partition. Can you please elaborate.
