The dw_hdmi-rockchip driver validates pixel clock rates against the HDMI PHY's internal clock provider on certain SoCs like RK3328. This is currently achieved by dereferencing hdmi->phy->dev.of_node to obtain the provider node, which violates the Generic PHY API's encapsulation (the goal is for struct phy to be an opaque pointer with a hidden definition, to be interacted with only using API functions or NULL pointer checks, for the case where optional variants of phy_get() did not find a PHY). Refactor dw_hdmi_rockchip_bind() to perform a manual phandle lookup on the "hdmi" PHY index within the controller's DT node. This provides a parallel path to the clock provider's OF node without relying on the internal structure of the struct phy handle.
