Yes, exactly. I could have just fixed sf.c which is the one I need for
my current project, but it turns out that without the ability to say
CONFIG_IS_ENABLED(SAVEENV) the changes to sf.c would be significantly
uglier, so it seemed better to provide the infrastructure that will also
be useful for converting other storage drivers to honour CONFIG_SPL_SAVEENV.
