[PATCH] powerpc: pseries/smp: query-cpu-stopped-state support won't change

[Milton Miller <miltonm@bga.com>]

If a given firmware doesn't have a token to support query-cpu-stopped-state,
its not likely to change during the lifetime of the kernel.   

Only print this information once, not once per secondary thread.

While here, make the line wrap grep friendly.
