zinger: change watchdog timeout to 1.8 second
Increase watchdog timeout to 1.8 second. The pd_task can delay up
to 1.5 seconds, so the watchdog must be at least that value.
On Zinger, the new timeout period will be 2 seconds with LSI clock at 50kHz
and 3.36 seconds with LSI clock at 30kHz.
Note: the LSI frequency range is tighter on STM32F0 and cannot go up to
56kHz.
BUG=none
BRANCH=none
TEST=add 1.5 second blocking delay to pd_task and make sure
watchdog is normally not firing.
