stm32: unimplemented hibernate hard-reboots instead of hangingtoolchainAstabilize-3912.79.Brelease-R27-3912.B
This more closely emulates what LM4 does if it hibernates and then
immediately wakes. Keeps the system from becoming silently
unresponsive if a hibernate is triggered on STM32.
BUG=chrome-os-partner:18371
BRANCH=none
TEST=from ec console, 'hibernate' reboots instead of hanging
