Randall Spangler 433f98c6b6 Add per-second hook ...

PWM and temp sensor monitoring want to happen every second,
vs. several times a second for watchdog and LPC.

This is still considerably simpler than having tick functions declare
an interval at which they want to be called, which would require a
RAM-based array of pending tick functions and alarm times.  If you
need that level of complexity, you still need a task.

BUG=chrome-os-partner:15714
BRANCH=none

TEST=temporarily add HOOK_TICK and HOOK_SECOND hooks and see that on
LM4, HOOK_TICK is called 4x a second and HOOK_SECOND is called every
second.
