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.
