[PATCH] PowerMac: force only suspend-to-disk to be valid
For a very long time, echoing 'standby' or 'mem' into /sys/power/state has
killed the machine on powerpc. This patch fixes that.
This patch adds the .valid callback to pm_ops on PowerMac so that only the
suspend to disk state can be entered. Note that just returning 0 would
suffice since the upper layers don't pass PM_SUSPEND_DISK down, but we
handle it there regardless just in case that changes.
