[PATCH v4 2/3] media: nxp: imx8-isi: Add 16-bit raw Bayer format support

From: Laurentiu Palcu <[email protected]>

Add support for 16-bit raw Bayer formats (SBGGR16, SGBRG16, SGRBG16,
SRGGB16) to both the pipeline subdev and video capture interface.

These formats are used by image sensors that output 16-bit raw data,
enabling the ISI to capture full dynamic range from such sensors.
