thermal: core: Eliminate thermal_zone_trip_down()

Since thermal_zone_set_trip_temp() is now located in the same file
as thermal_trip_crossed(), it can invoke the latter directly without
using the thermal_zone_trip_down() wrapper that has no other users.

Update thermal_zone_set_trip_temp() accordingly and drop
thermal_zone_trip_down().

No functional impact.
