dt-bindings: phy: rk3228-hdmi-phy: convert to yaml

Convert the binding to yaml and rename it according to its first
compatible instead of the unspecific rockchip-inno-hdmi naming.

-ROCKCHIP HDMI PHY WITH INNO IP BLOCK
-
-Required properties:
- - compatible : should be one of the listed compatibles:
-       * "rockchip,rk3228-hdmi-phy",
-       * "rockchip,rk3328-hdmi-phy";
- - reg : Address and length of the hdmi phy control register set
- - clocks : phandle + clock specifier for the phy clocks
- - clock-names : string, clock name, must contain "sysclk" for system
-         control and register configuration, "refoclk" for crystal-
-         oscillator reference PLL clock input and "refpclk" for pclk-
-         based refeference PLL clock input.
- - #clock-cells: should be 0.
- - clock-output-names : shall be the name for the output clock.
- - interrupts : phandle + interrupt specified for the hdmiphy interrupt
- - #phy-cells : must be 0. See ./phy-bindings.txt for details.
-
-Optional properties for rk3328-hdmi-phy:
- - nvmem-cells = phandle + nvmem specifier for the cpu-version efuse
- - nvmem-cell-names : "cpu-version" to read the chip version, required
-         for adjustment to some frequency settings
-
-Example:
-       hdmi_phy: hdmi-phy@12030000 {
-               compatible = "rockchip,rk3228-hdmi-phy";
-               reg = <0x12030000 0x10000>;
-               #phy-cells = <0>;
-               clocks = <&cru PCLK_HDMI_PHY>, <&xin24m>, <&cru DCLK_HDMIPHY>;
-               clock-names = "sysclk", "refoclk", "refpclk";
-               #clock-cells = <0>;
-               clock-output-names = "hdmi_phy";
-               status = "disabled";
-       };
-
-Then the PHY can be used in other nodes such as:
-
-       hdmi: hdmi@200a0000 {
-               compatible = "rockchip,rk3228-dw-hdmi";
-               ...
-               phys = <&hdmi_phy>;
-               phy-names = "hdmi";
-               ...
-       };
