env: Drop DELAY_ENVIRONMENT

Browse Source 
There are no users of DELAY_ENVIRONMENT and the same effect can
be achieved either using DT /config/load-environment property,
or by using ENV_IS_NOWHERE . Remove this configuration option
and matching functionality.

explicitly loaded later by U-Boot code. With CONFIG_OF_CONTROL

Enable this to inhibit loading the environment during board
initialization. This can address the security risk of untrusted data
being used during boot. Normally the environment is loaded when the
board is initialised so that it is available to U-Boot. This inhibits
that so that the environment is not available until explicitly loaded
later by U-Boot code. With CONFIG_OF_CONTROL this is instead
