watchdog: Give more leeway to the independent watchdog
It would be really nice to be guaranteed to see watchdog warnings
before we actually hit a watchdog reset even if something strange is
going on with the CPU. Let's increase the margin between the timer
and the independent so that the hardware watchdog is really hit as a
last resort.
It seems like a 1.6 second hardware watchdog wouldn't be the end of
the world so let's bump that way rather than increasing the number of
warnings.
BRANCH=ToT
BUG=chrome-os-partner:29162
TEST="waitms 1000" on EC console no longer ever reboots and "waitms
2000" usually does.
