staging: wilc1000: use YAML schemas for DT binding documentation

Use YAML schemas for wilc1000 DT binding documentations. Currently, the
files are present in '/drivers/staging/wilc1000/' but these will be
moved to '/Documentation/devicetree/bindings/net/wireless/' later once
the driver move out-of-staging.

-* Microchip WILC wireless SDIO device
-
-The wilc1000 chips can be connected via SDIO. The node is used to specifiy
-child node to the SDIO controller that connects the device to the system.
-
-Required properties:
-- compatible	:	Should be "microchip,wilc1000-spi"
-- irq-gpios	:	Connect to a host IRQ
-- reg		:	Slot ID used in the controller
-
-Optional:
-- bus-width	:	Number of data lines wired up the slot. Default 1 bit.
-- rtc_clk	:	Clock connected on the rtc clock line. Must be assigned
-			a frequency with assigned-clocks property, and must be
-			connected to a clock provider.
-
-Examples:
-mmc1: mmc@fc000000 {
-		pinctrl-names = "default";
-		pinctrl-0 = <&pinctrl_mmc1_clk_cmd_dat0 &pinctrl_mmc1_dat1_3>;
-		non-removable;
-		vmmc-supply = <&vcc_mmc1_reg>;
-		vqmmc-supply = <&vcc_3v3_reg>;
-		status = "okay";
-
-		wilc_sdio@0 {
-			compatible = "microchip,wilc1000-sdio";
-			irq-gpios = <&pioC 27 0>;
-			clocks = <&pck1>;
-			clock-names = "rtc_clk";
-			assigned-clocks = <&pck1>;
-			assigned-clock-rates = <32768>;
-			status = "okay";
-			reg = <0>;
-			bus-width = <4>;
-		}
-	};

-* Microchip WILC wireless SPI device
-
-The wilc1000 chips can be connected via SPI. This document describes
-the binding for the SPI connected module.
-
-Required properties:
-- compatible		: Should be "microchip,wilc1000-spi"
-- spi-max-frequency	: Maximum SPI clocking speed of device in Hz
-- reg			: Chip select address of device
-- irq-gpios		: Connect to a host IRQ
-
-Optional:
-- rtc_clk	:	Clock connected on the rtc clock line. Must be assigned
-			a frequency with assigned-clocks property, and must be
-			connected to a clock provider.
-
-Examples:
-
-spi1: spi@fc018000 {
-		cs-gpios = <&pioB 21 0>;
-		status = "okay";
-
