  Add device tree bindings for the video clock controller on Qualcomm
SM8450 platform.

Changes since V3:
 - None.

Changes since V2:
 - As per Stephen's comments drop clock-names to match how newer
   qcom clk bindings are being done.
 - Change the header file name as qcom,sm8450-videocc.h to match
   latest upstream header files.

Changes since V1:
 - Change the properties order to keep reg after the compatible
   property.
