Convert ADV748X analog video decoder documentation to json-schema.

Hello,
This conversion revealed a problem with the Renesas DTSI files for the
adv7482 nodes. A fix for that have been submitted in a separate patch,
[PATCH] arm64: dts: renesas: Add ports node to all adv7482 nodes
Kind Regards,
Niklas Söderlund

-* Analog Devices ADV748X video decoder with HDMI receiver
-
-The ADV7481 and ADV7482 are multi format video decoders with an integrated
-HDMI receiver. They can output CSI-2 on two independent outputs TXA and TXB
-from three input sources HDMI, analog and TTL.
-
-Required Properties:
-
- - compatible: Must contain one of the following
- - "adi,adv7481" for the ADV7481
- - "adi,adv7482" for the ADV7482
-
- - reg: I2C slave addresses
- The ADV748x has up to twelve 256-byte maps that can be accessed via the
- main I2C ports. Each map has it own I2C address and acts as a standard
- slave device on the I2C bus. The main address is mandatory, others are
- optional and remain at default values if not specified.
-
-Optional Properties:
-
- - interrupt-names: Should specify the interrupts as "intrq1", "intrq2" and/or
- "intrq3". All interrupts are optional. The "intrq3" interrupt
- is only available on the adv7481
- - interrupts: Specify the interrupt lines for the ADV748x
- - reg-names : Names of maps with programmable addresses.
- It shall contain all maps needing a non-default address.
- Possible map names are:
- "main", "dpll", "cp", "hdmi", "edid", "repeater",
- "infoframe", "cbus", "cec", "sdp", "txa", "txb"
-
-The device node must contain one 'port' child node per device input and output
-port, in accordance with the video interface bindings defined in
-Documentation/devicetree/bindings/media/video-interfaces.txt. The port nodes
-are numbered as follows.
-
- Name Type Port
- ---------------------------------------
- AIN0 sink 0
- AIN1 sink 1
- AIN2 sink 2
- AIN3 sink 3
- AIN4 sink 4
- AIN5 sink 5
- AIN6 sink 6
- AIN7 sink 7
- HDMI sink 8
- TTL sink 9
- TXA source 10
- TXB source 11
-
-The digital output port nodes, when present, shall contain at least one
-endpoint. Each of those endpoints shall contain the data-lanes property as
-described in video-interfaces.txt.
-
-Required source endpoint properties:
- - data-lanes: an array of physical data lane indexes
- The accepted value(s) for this property depends on which of the two
- sources are described. For TXA 1, 2 or 4 data lanes can be described
- while for TXB only 1 data lane is valid. See video-interfaces.txt
- for detailed description.
-
-Ports are optional if they are not connected to anything at the hardware level.
-
-Example:
-
- video-receiver@70 {
- compatible = "adi,adv7482";
- reg = <0x70 0x71 0x72 0x73 0x74 0x75
- 0x60 0x61 0x62 0x63 0x64 0x65>;
- reg-names = "main", "dpll", "cp", "hdmi", "edid", "repeater",
- "infoframe", "cbus", "cec", "sdp", "txa", "txb";
-
- #address-cells = <1>;
- #size-cells = <0>;
-
- interrupt-parent = <&gpio6>;
- interrupt-names = "intrq1", "intrq2";
- interrupts = <30 IRQ_TYPE_LEVEL_LOW>,
- <31 IRQ_TYPE_LEVEL_LOW>;
-
- port@7 {
- reg = <7>;
-
- adv7482_ain7: endpoint {
- remote-endpoint = <&cvbs_in>;
- };
- };
-
- port@8 {
- reg = <8>;
-
- adv7482_hdmi: endpoint {
- remote-endpoint = <&hdmi_in>;
- };
- };

- adv7482_txa: endpoint {
- clock-lanes = <0>;
- data-lanes = <1 2 3 4>;
- remote-endpoint = <&csi40_in>;

-
- adv7482_txb: endpoint {
- clock-lanes = <0>;
- data-lanes = <1>;
- remote-endpoint = <&csi20_in>;
