[PATCH v2 06/14] arm64: dts: rockchip: Remove #cooling-cells from fan on Theobroma boards

All Theobroma boards use a ti,amc6821 as fan controller.
It normally runs in an automatically controlled way and while it may be
possible to use it as part of a dt-based thermal management, this is
not yet specified in the binding, nor implemented in any kernel.

Newer boards already don't contain that #cooling-cells property, but
older ones do. So remove them for now, they can be re-added if thermal
integration gets implemented in the future.
