Subject: [PATCH v3 3/3] media: nxp: imx8-isi: Add ISI support for i.MX95

From: Guoniu Zhou <guoniu.zhou@....com>

The ISI module on i.MX95 supports up to eight channels and four link
sources to obtain the image data for processing in its pipelines. It
can process up to eight image sources at the same time.

Add ISI basic functions support for i.MX95.
