The DPTF framework will sometimes set thresholds and not expect
to get another event if the current temperature is above both the
previous threshold and the new threshold.
When a threshold is set only initialize the over condition if the
threshold was previously disabled in order to prevent it from
firing again.

Vboot hash calculation takes ~350 ms during EC boot. Since the hash
task is higher priority than the hook task, this starves all the hooks
during boot.
We could, in theory, fix that simply by swapping the priority of the
hook and hash tasks. But then watchdog detection (in the hook task)
wouldn't detect hangs in the hash task.
A better fix (implemented here) is to convert the hashing operation to
a series of deferred function calls. This gets rid of the hash task
entirely, and allows all pending hooks and other deferred function
calls to take place between each chunk of hashing.
On STM32-based boards, we need to bump up the hook task stack size,
since hashing is called from several layers deep in the hook task
instead of at the top of its own task, but this is still a net win of
several hundred bytes of SRAM.

This lowers, the WARN, HIGH, and HALT temp thresholds

Also lowers the FAN_MIN and FAN_MAX temps by 5 degrees on
Haswell boards to compensate for lowering TJ_MAX by 5 degrees
in an earlier patch.
