ryu: disable system hibernate
Hibernate is not supported on STM32F0. Disable system hibernate so that
the system doesn't auto-reboot after an hour in G3. This also benefits
us in terms of firmware size.
BUG=chrome-os-partner:31665
TEST=Boot on Ryu. Check 'hibdelay' and 'hibernate' commands are absent.
TEST=Boot Ryu from G3.
TEST=Change default hibernation delay to 1 second. Put system in G3.
Check it does not reboot.
BRANCH=None
