Increase cold reset hibernate time to 200msstabilize2
The hardware fix for issue 16600 adds RC delays to ENABLE_5VALW, so
that +5VALW stays on during a warm reset of the EC. In the worst
case, +5VALW will drop around 150ms, which could then move the +3VALW
glitch right into the time frame where the EC is booting following
hibernate.
Increase the cold reset hibernate time from 150ms to 200ms. This
ensures that +5VALW has dropped before the EC comes out of hibernate.
BUG=chrome-os-partner:16600
BRANCH=link
TEST=manual
From the EC console, 'reboot cold' a bunch of times. The system
shouldn't hang. (Alternately, you can 'ectool reboot_ec cold' a bunch
of times)
