[PATCH] kernel/power/suspend: use CONFIG_HAVE_SET_MEMORY for include condition

[Balbir Singh <bsingharora@gmail.com>]

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.

fixes(50327dd kernel/power/snapshot.c: use set_memory.h header)

I've only done a basic compile test with a config that has
hibernation enabled.
