libcamera: pipeline: simple: Add support for NXP ISI

Several NXP i.MX8 SoCs (such as the i.MX8MN and i.MX8MP) contain a
camera pipeline made of sensor interfaces (with parallel and/or CSI-2
receivers) and an image processing engine named ISI. The ISI contains an
input crossbar switch and one or more processing pipelines capable of
format conversion and scaling.

This is a good candidate for the simple pipeline handler as a first
step. The i.MX8MP should eventually graduate to having its own pipeline
handler as it also contains two ISP instances (supported by the rkisp1
driver).
