powerpc: Disable VPHN polling during a suspend operation
Tie the polling mechanism into the ibm,suspend-me rtas call to stop/restart polling before/after a suspend, hibernate, migrate, or checkpoint restart operation. This ensures that the system has a chance to disable the polling if the partition is migrated to a system that does not support VPHN (and vice versa).
