dt-bindings: display: samsung,exynos-hdmi: convert to dtschema

Convert the Exynos HDMI bindings to DT schema format.

The conversion includes also updates to the bindings, matching the
current DTS and Linux driver:
1. Add required properties: VDD supplies, power-domains.
2. Add optional properties: HDMI-EN supply, ports.

-Device-Tree bindings for drm hdmi driver
-
-Required properties:
-- compatible: value should be one among the following:
-	1) "samsung,exynos4210-hdmi"
-	2) "samsung,exynos4212-hdmi"
-	3) "samsung,exynos5420-hdmi"
-	4) "samsung,exynos5433-hdmi"
-- reg: physical base address of the hdmi and length of memory mapped
-	region.
-- interrupts: interrupt number to the cpu.
-- hpd-gpios: following information about the hotplug gpio pin.
-	a) phandle of the gpio controller node.
-	b) pin number within the gpio controller.
-	c) optional flags and pull up/down.
-- ddc: phandle to the hdmi ddc node
-- phy: phandle to the hdmi phy node
-- samsung,syscon-phandle: phandle for system controller node for PMU.
-- #sound-dai-cells: should be 0.
-
-Required properties for Exynos 4210, 4212, 5420 and 5433:
-- clocks: list of clock IDs from SoC clock driver.
-	a) hdmi: Gate of HDMI IP bus clock.
-	b) sclk_hdmi: Gate of HDMI special clock.
-	c) sclk_pixel: Pixel special clock, one of the two possible inputs of
-		HDMI clock mux.
-	d) sclk_hdmiphy: HDMI PHY clock output, one of two possible inputs of
-		HDMI clock mux.
-	e) mout_hdmi: It is required by the driver to switch between the 2
-		parents i.e. sclk_pixel and sclk_hdmiphy. If hdmiphy is stable
-		after configuration, parent is set to sclk_hdmiphy else
-		sclk_pixel.
-- clock-names: aliases as per driver requirements for above clock IDs:
-	"hdmi", "sclk_hdmi", "sclk_pixel", "sclk_hdmiphy" and "mout_hdmi".
-
-Required properties for Exynos 5433:
-- clocks: list of clock specifiers according to common clock bindings.
-	a) hdmi_pclk: Gate of HDMI IP APB bus.
-	b) hdmi_i_pclk: Gate of HDMI-PHY IP APB bus.
-	d) i_tmds_clk: Gate of HDMI TMDS clock.
-	e) i_pixel_clk: Gate of HDMI pixel clock.
-	f) i_spdif_clk: Gate of HDMI SPDIF clock.
-	g) oscclk: Oscillator clock, used as parent of following *_user clocks
-		in case HDMI-PHY is not operational.
-	h) tmds_clko: TMDS clock generated by HDMI-PHY.
-	i) tmds_clko_user: MUX used to switch between oscclk and tmds_clko,
-		respectively if HDMI-PHY is off and operational.
-	j) pixel_clko: Pixel clock generated by HDMI-PHY.
-	k) pixel_clko_user: MUX used to switch between oscclk and pixel_clko,
-		respectively if HDMI-PHY is off and operational.
-- clock-names: aliases for above clock specfiers.
-- samsung,sysreg: handle to syscon used to control the system registers.

-Example:
-
-	hdmi {
-		compatible = "samsung,exynos4212-hdmi";
-		reg = <0x14530000 0x100000>;
-		interrupts = <0 95 0>;
-		hpd-gpios = <&gpx3 7 1>;
-		ddc = <&hdmi_ddc_node>;
-		phy = <&hdmi_phy_node>;
-		samsung,syscon-phandle = <&pmu_system_controller>;
-	};
