    thermal: trip: Split thermal_zone_device_set_mode()
    
    [ Upstream commit e5f98896efb3b6350cb6f1c241394966dcbcf240 ]
    
    Pull a wrapper around thermal zone .change_mode() callback out of
    thermal_zone_device_set_mode() because it will be used elsewhere
    subsequently.
    
    No intentional functional impact.
