[PATCH v2 02/15] dt-bindings: display: bridge: Add starfive,jh7110-inno-hdmi-controller

[Michal Wilczynski]

Add the dt-binding for the StarFive JH7110 Innosilicon HDMI controller
(DRM bridge).

This device is the second child of the starfive,jh7110-hdmi-subsystem node.
It consumes register access clocks (sys, mclk, bclk) from the voutcrg and
both the pixel clock (pclk) and the PHY from its hdmi_phy sibling.
