Crap can work. Given enough thrust pigs will fly, but it's not necessarily a
good idea. [ RFC1925, 2.3 ]

While it is true that Ingenic SoCs support huge pages, we cannot use
them yet as PTEs don't have any single bit that is free. Right now,
having that symbol only causes build errors, so remove it until the
situation with PTEs is resolved.
