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 */
};
