env: Add support for explicit write access list This option marks any U-Boot variable which does not have explicit 'w' writeable flag set as read-only. This way the environment can be locked down and only variables explicitly configured to be writeable can ever be changed by either 'env import', 'env set' or loading user environment from environment storage.
