Add the dt-binding for the StarFive JH7110 HDMI subsystem.
The JH7110 HDMI IP is a monolithic block containing both the digital
controller and analog PHY in a single register space. This binding
defines the parent device, which holds the shared register map, and its
two children: the PHY and the controller.
The two have separate resources. The PHY takes the 24 MHz reference
clock and provides both the pixel clock, which the VOUT clock generator
routes on to the display controller, and the phy the controller uses.
The controller takes its clocks from the VOUT clock generator. What
they share is the register space, which the parent maps.

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.
If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:
pip3 install dtschema --upgrade
Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.
