env: Add CONFIG_ENV_SUPPORT
Add a new flag CONFIG_ENV_SUPPORT to compile all
the environment features in U-Boot (attributes, callbacks
and flags); it is the supplement of the 2 existing flags
for SPL/TPL.
To have ENV support, enable the flag:
- CONFIG_ENV_SUPPORT for U-Boot proper
- CONFIG_SPL_ENV_SUPPORT for SPL
- CONFIG_TPL_ENV_SUPPORT for TPL
This new configuration allows to use the macro
CONFIG_IS_ENABLED(ENV_SUPPORT) in the code without
issue and solves the regression introduced by
commit 7d4776545b0f ("env: solve compilation error
in SPL"); change_ok was always NULL in U-Boot.
