[PATCH] ppc32: Fix a sleep issues on some laptops

Some earlier models of aluminium powerbooks and ibook G4s have a clock chip
that requires some tweaking before and after sleep.  It seems that without
that magic incantation to disable and re-enable clock spreading, RAM isn't
properly refreshed during sleep.  This fixes it.
