dt-bindings: Remove unused Sigma Designs Tango bindings 



The Sigma Designs Tango support has been removed, but 2 binding docs
for NAND and PCIe were missed. Remove them.

Sigma Designs Tango4 NAND Flash Controller (NFC)



Required properties:



- compatible: "sigma,smp8758-nand"

- reg: address/size of nfc_reg, nfc_mem, and pbus_reg

- dmas: reference to the DMA channel used by the controller

- dma-names: "rxtx"

- clocks: reference to the system clock

- #address-cells: <1>

- #size-cells: <0>



Children nodes represent the available NAND chips.

See Documentation/devicetree/bindings/mtd/nand-controller.yaml for generic bindings.



Example:



	nandc: nand-controller@2c000 {

		compatible = "sigma,smp8758-nand";

		reg = <0x2c000 0x30>, <0x2d000 0x800>, <0x20000 0x1000>;

		dmas = <&dma0 3>;

		dma-names = "rxtx";

		clocks = <&clkgen SYS_CLK>;

		#address-cells = <1>;

		#size-cells = <0>;



		nand@0 {

			reg = <0>; /* CS0 */

			nand-ecc-strength = <14>;

			nand-ecc-step-size = <1024>;

		};



		nand@1 {

			reg = <1>; /* CS1 */

			nand-ecc-strength = <14>;

			nand-ecc-step-size = <1024>;

		};

	};

Sigma Designs Tango PCIe controller



Required properties:



- compatible: "sigma,smp8759-pcie"

- reg: address/size of PCI configuration space, address/size of register area

- bus-range: defined by size of PCI configuration space

- device_type: "pci"

- #size-cells: <2>

- #address-cells: <3>

- msi-controller

- ranges: translation from system to bus addresses

- interrupts: spec for misc interrupts, spec for MSI



Example:



	pcie@2e000 {

		compatible = "sigma,smp8759-pcie";

		reg = <0x50000000 0x400000>, <0x2e000 0x100>;

		bus-range = <0 3>;

		device_type = "pci";

		#size-cells = <2>;

		#address-cells = <3>;

		msi-controller;

		ranges = <0x02000000 0x0 0x00400000  0x50400000  0x0 0x3c00000>;

		interrupts =

			<54 IRQ_TYPE_LEVEL_HIGH>, /* misc interrupts */

			<55 IRQ_TYPE_LEVEL_HIGH>; /* MSI */

	};
