dt-bindings: ata: rcar-sata: Convert to json-schema 



Convert the Renesas R-Car Serial-ATA Device Tree binding documentation
to json-schema.

While at it:
  - Remove the deprecated "renesas,rcar-sata" compatible value,
  - Add "iommus", "power-domains", and "resets" properties,
  - Update the example.

* Renesas R-Car SATA



Required properties:

- compatible		: should contain one or more of the following:

			  - "renesas,sata-r8a774b1" for RZ/G2N

			  - "renesas,sata-r8a7779" for R-Car H1

			  - "renesas,sata-r8a7790-es1" for R-Car H2 ES1

			  - "renesas,sata-r8a7790" for R-Car H2 other than ES1

			  - "renesas,sata-r8a7791" for R-Car M2-W

			  - "renesas,sata-r8a7793" for R-Car M2-N

			  - "renesas,sata-r8a7795" for R-Car H3

			  - "renesas,sata-r8a77965" for R-Car M3-N

			  - "renesas,rcar-gen2-sata" for a generic R-Car Gen2

			     compatible device

			  - "renesas,rcar-gen3-sata" for a generic R-Car Gen3 or

			     RZ/G2 compatible device

			  - "renesas,rcar-sata" is deprecated



			  When compatible with the generic version nodes

			  must list the SoC-specific version corresponding

			  to the platform first followed by the generic

			  version.



- reg			: address and length of the SATA registers;

- interrupts		: must consist of one interrupt specifier.

- clocks		: must contain a reference to the functional clock.



Example:



sata0: sata@ee300000 {

	compatible = "renesas,sata-r8a7791", "renesas,rcar-gen2-sata";

	reg = <0 0xee300000 0 0x2000>;

	interrupt-parent = <&gic>;

	interrupts = <0 105 IRQ_TYPE_LEVEL_HIGH>;

	clocks = <&mstp8_clks R8A7791_CLK_SATA0>;

};
