Frank Li c4891010d8 media: dt-bindings: Add binding doc for i.MX8QXP and i.MX8QM ISI
Add binding documentation for i.MX8QXP and i.MX8QM ISI. The clock-names,
power-domains, and ports differ significantly from the existing
nxp,imx8-isi.yaml. Create a new file to avoid complex if-else branches.

Add new file to MAINTAINERS.

title: i.MX8QM Image Sensing Interface
maintainers:
- Frank Li <Frank.Li@nxp.com>
description:
The Image Sensing Interface (ISI) combines image processing pipelines with
DMA engines to process and capture frames originating from a variety of
sources. The inputs to the ISI go through Pixel Link interfaces, and their
number and nature is SoC-dependent. They cover both capture interfaces (MIPI
CSI-2 RX, HDMI RX, ...) and display engine outputs for writeback support.
