Commit 65184f2f authored by Christophe Leroy's avatar Christophe Leroy Committed by Michael Ellerman

powerpc/setup: replace ifdefs by IS_ENABLED() wherever possible.

Compared to ifdefs, IS_ENABLED() provide a cleaner code and allows
to detect compilation failure regardless of the selected options.
