x86/S3: add cache flush on secondary CPUs before going to sleep
Secondary CPUs, between doing their final memory writes (particularly
updating cpu_initialized) and getting a subsequent INIT, may not write
back all modified data. The INIT itself then causes those modifications
to be lost, so in the cpu_initialized case the CPU would find itself
already initialized, (intentionally) entering an infinite loop instead
of actually coming online.

Make acpi_dead_idle() call default_dead_idle() rather than duplicating
the logic there.
