This is a patch for cpuidle flow when KASAN enable, that is in ARM64
but not in ARM, so add to ARM.

The reference commits did not mention fix any commits.
[1] commit 0d97e6d8024c ("arm64: kasan: clear stale stack poison")
[2] commit d56a9ef84bd0 ("kasan, arm64: unpoison stack only with
CONFIG_KASAN_STACK")
