ite: Watchdog module added
Watchdog module added. Off by default because of following limitations:
- When programming, the WD fires, and programming fails. For now, you
have to program twice.
BRANCH=none
BUG=chrome-os-partner:23575
TEST=Manually wrote in a while(1); and made sure watchdog warning
triggers first, prints IPC register, and then soon after the watchdog
timer resets the chip.
