The "env info" can be use for test with -d and -p parameter, in scripting case the output of the command is not needed.

This patch allows to deactivate this output with a new option "-q".

For example, we can save the environment if default environment is used and persistent storage is managed with: if env info -p -d -q; then env save; fi

Without the quiet option, I have the unnecessary traces First boot: Default environment is used Environment can be persisted Saving Environment to EXT4... File System is consistent

Next boot: Environment was loaded from persistent storage Environment can be persisted

Check the current ENV location, dynamically provided by the weak function env_get_location to be sure that the environment can be persistent.

The compilation flag ENV_IS_IN_DEVICE is not enough when the board dynamically select the available storage location (according boot device for example).

This patch solves issue for stm32mp1 platform, when the boot device is USB.

Activate CMD_NVEDIT_INFO and use the new command "env info -d -p -q" to automatically save the environment on first boot.

This patch allows to remove the env_default variable.
