[v5,04/30] thermal/core: Add a generic thermal_zone_get_crit_temp() function

Commit Message

The thermal zone ops defines a callback to retrieve the critical
temperature. As the trip handling is being reworked, all the trip
points will be the same whatever the driver and consequently finding
the critical trip temperature will be just a loop to search for a
critical trip point type.

Provide such a generic function, so we encapsulate the ops
get_crit_temp() which can be removed when all the backend drivers are
using the generic trip points handling.

Well, this only adds a function header which by itself is not
particularly useful (and the code change doesn't match the changelog
even), so I would fold it into the patch that actually adds the
function, including its body.
