It's a matter of how it gets represented in Kconfig. Right now the ARCH_NEEDS_CPU_IDLE_COUPLED symbol has a dependency on CPU_IDLE, so we cannot select it if CPU_IDLE is not set (or get a build time warning).
I originally suggested removing the dependency, but Daniel preferred to leave it there as an explicit dependency so it is required to do this change instead.
