[v3,00/33] media: atmel: atmel-isc: add support for xisc

Hello,

This series adds support for a variant of the ISC named XISC.
This block is present in the product named sama7g5.

I started by moving code around, the code which was specialized for sama5d2
type of ISC, to have it inside the dedicated sama5d2 file.

I added several new pipeline elements to the code base, which would be common
to sama5d2 and the new sama7g5, but only used by the new style pipeline.

I separated the input and output formats on a per-product separate array.

I added the new sama7g5 compatible driver for the xisc, which is similar with
the sama5d2, but with differences in terms of DT, clocks and callbacks to
specific operations.

I converted the atmel-isc binding to yaml format, and added the new binding in yaml
format.

Feedback is appreciated.
Thanks,
Eugen

Changes in v3:
- Adapted commit messages for several commits to explain several acronyms, especially
for submodule names
- Converted atmel-isc binding to yaml
- Converted microchip-xisc binding to yaml
- Updated MAINTAINERS

Changes in v2:
- Fixed krobot warnings with W=1 regarding functions with no prototype
- Fixed new sama7g5 driver to use the new subdev fwnode API in kernel 5.12. my driver was
based on old 5.10 style API.
