[PATCH v4 15/15] arm64: dts: sc7180: Add clock controller nodes

[Douglas Anderson]

From: Taniya Das <tdas@xxxxxxxxxxxxxx>

Add the display, video & graphics clock controller nodes supported on
SC7180.

NOTE: the dispcc needs input clocks from various PHYs that aren't in
the device tree yet.  For now we'll leave these stubbed out with <0>,
which is apparently the magic way to do this.  These clocks aren't
really "optional" and this stubbing out method is apparently the best
way to handle it.

Changes in v4: None
Changes in v3:
- Added videocc include file.
- Unlike in v2, use internal name instead of purist name.

Changes in v2:
- Added includes
- Changed various parent names to match bindings / driver
