3.11.10.13 -stable review patch.  If anyone has any objections, please let me 
know.

------------------

From: gundberg <[email protected]>

commit a9e0436b303e94ba57d3bd4b1fcbeaa744b7ebeb upstream.

Use the prescaler index, rather than its value, to configure the watchdog.
This will prevent a mismatch with the prescaler used to calculate the cycles.
