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 Change-Id: I9068ee99d56a5bf5c12afd86ad51998c013f4954 Signed-off-by: Randall Spangler <rspangler@chromium.org> Reviewed-on: https://gerrit.chromium.org/gerrit/36908 Reviewed-by: Simon Glass <sjg@chromium.org>
