spi: dt-bindings: convert spi-sc18is602.txt to yaml format 



Convert binding doc spi-sc18is602.txt (I2C to SPI bridge) to yaml.

Additional change:
- ref spi-controller.yaml

Fix below warning:
arch/arm64/boot/dts/freescale/fsl-lx2160a-bluebox3.dtb:
/soc/i2c@2000000/i2c-mux@77/i2c@7/i2c-mux@75/i2c@0/spi@28: failed to match any schema with compatible: ['nxp,sc18is602b']

Required properties:

	- compatible : Should be one of

		"nxp,sc18is602"

		"nxp,sc18is602b"

		"nxp,sc18is603"

	- reg: I2C bus address



Optional properties:

	- clock-frequency : external oscillator clock frequency. If not

	  specified, the SC18IS602 default frequency (7372000) will be used.



The clock-frequency property is relevant and needed only if the chip has an

external oscillator (SC18IS603).



Example:



	sc18is603@28 {

		compatible = "nxp,sc18is603";

		reg = <0x28>;

		clock-frequency = <14744000>;

	}
