PM / hibernate: Use CONFIG_HAVE_SET_MEMORY for include condition
Kbuild reported a build failure when CONFIG_STRICT_KERNEL_RWX was enabled on powerpc. We don't yet have ARCH_HAS_SET_MEMORY and ppc32 saw a build failure. I've only done a basic compile test with a config that has hibernation enabled.
