system: Add hibernate board-level callback
Allow boards to take action (such as entering a custom low-power
hibernate-like state) before putting the chip into hibernate state.
BUG=chrome-os-partner:56070
BRANCH=firmware-strago-7287.B
TEST=Manual with subsequent commit on chell. Verify board-level
hibernate callback is called when "hibernate" is run on EC console.
Ported from the master branch to strago branch.
