powerpc: Clean up panic_timeout usage
Default CONFIG_PANIC_TIMEOUT to 180 seconds on powerpc. The
pSeries continue to set the timeout to 10 seconds at run-time.
Thus, there's a small window where we don't have the correct
value on pSeries, but if this is only run-time discoverable we
don't have a better option. In any case, if the user changes the
default setting of 180 seconds, we honor that user setting.
