[PATCH v2 01/15] dt-bindings: phy: Add starfive,jh7110-inno-hdmi-phy

Add the dt-binding for the StarFive JH7110 Innosilicon HDMI PHY.

This device is a child of the starfive,jh7110-hdmi-subsystem node. It
functions as both a PHY provider for the controller and as a clock
provider for the variable pixel clock (hdmi_pclk), which it generates
from its refoclk.
