Did you even try this patch?

Did you try to select UCC_GETH and see if UCC_FAST got
automatically selected or not?

Did you get any build problems (or bogus warnings, for that matter)?

Have you ever looked into arch/.../Kconfig's?

This is precisely what happens with this patch too.

Believe me, just go ahead and try it.

Report any errors, dissatisfaction, etc, if any.

Thanks.

[ Just to add: ]

You'll learn about the "default .. if .." Kconfig idiom after you try this, but
when this patch works for you, an Acked-by would also be nice, thanks.
