[ Upstream commit 1d2f14117aa7773efff50f832b85fc7779e586e0 ]
Add an active trip tied to the on-board fan cooling device, which is better
than describing it along the passive cooling maps.
Fixes: 33b14f663df8 ("arm64: dts: meson: add initial device-tree for ODROID-HC4")
Reported-by: Ricardo Pardini <ricardo@xxxxxxxxxxx>
