Add tick task
Adds a new HOOK_TICK event which is called every 250ms (LM4) or 500ms
(STM32). This will be used to consolidate a number of tasks which do
small amounts of work infrequently, and previously needed their own
task functions.
This CL adds the tick task; subsequent CLs will consolidate watchdog
and other tasks into tick hooks.
BUG=chrome-os-partner:15714
BRANCH=none
TEST=taskinfo shows TICK task as lowest priority
