* [PATCH] dt-bindings: gpu: arm,mali-utgard: add additional properties

In the old txt situation we add/describe only properties that are used
by the driver/hardware itself. With yaml it also filters things in a
node that are used by other drivers like 'assigned-clocks' and
'assigned-clock-rates' for some older Rockchip SoCs in 'gpu' nodes,
so add them to 'arm,mali-utgard.yaml'.

though the other option would be to just get rid assigned-clocks
in dt-node for utgard malis ;-)

Like any good gpu, lima should just use frequency scaling to achieve
suitable (fast <-> powersaving) frequencies and it looks like a set
of patches for this was posted in december already [0].

So I guess one could expect opp-based scaling to land at some point.
