dt-bindings: display: rockchip,inno-hdmi: Document RK3128 compatible
The integration for this SoC is different from the currently existing: It
needs it's PHY's reference clock rate to calculate the DDC bus frequency
correctly. The controller is also part of a powerdomain, so this gets added
as an mandatory property for this variant.
