Subject: [PATCH 1/1] 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@...0000/i2c-mux@...i2c@...2c-mux@...i2c@...pi@28: failed to match any schema with compatible: ['nxp,sc18is602b']
