This adds the video clock controller node to sdm845 based on the examples
in the bindings.

Did you mean to send "To:" Andy? Clk tree doesn't take these sorts of
dts patches.

Thanks Stephen for adding Andy.

Any reason not to include "#reset-cells = <1>;" here?  The bindings
list it as optional but I see no reason why we should leave it off.
The file "include/dt-bindings/clock/qcom,videocc-sdm845.h" seems to
include some #defines for resets.  Even though the driver doesn't seem
like it supports it yet, it still should be fine to list it here.

Please sort your new node by unit address.  Specifically "ab00000"
comes before "af00000", thus I would expect you to have your node
right before the dispcc.

We should update the binding to make it a required property. It doesn't
make any sense why that property would be optional given that the
hardware either has support for resets or it doesn't.
