[PATCH v4 5/6] dt-bindings: clock: Add Qcom SM8350 DISPCC bindings

[Robert Foss]

Add sm8350 DISPCC bindings, while these bindings are similar
to the sm8x50 bindings, the way clocks are represented has changed
in ABI incompatible ways.

hanges since v2
 - Add my SoB - Bjorn

Changes since v3
 - Separate from qcom,dispcc-sm8x50
 - Remove clock-names
 - Make example sm8350 based
 - Changed author to me due to size of changes
