No, "#ifdef CONFIG_FOO" is definitely not the same as "#if
CONFIG_IS_ENABLED(FOO)". Please have a look at the definition of
CONFIG_IS_ENABLED: [1].
"CONFIG_IS_ENABLED(FOO)" will resolve to 1 if CONFIG_SPL_FOO and
CONFIG_SPL_BUILD are defined.
"#ifdef CONFIG_FOO" will only resolve to 1 if CONFIG_FOO is defined.
