[PATCH 3/5] media: nxp: imx8-isi: Add 16-bit raw Bayer format support

[guoniu . zhou]

From: Laurentiu Palcu <laurentiu.palcu@xxxxxxxxxxx>

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

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