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 populates its two children: the PHY and the controller. This is necessary to resolve a circular clock dependency between the HDMI block and the VOUT clock generator.
