Add the Gen4 family compatible. This will be used instead of a SoC
specific compatible for the new Gen4 SoC V4M being added. As the first
Gen4 board V4H had already been added prior to the Gen4 family fallback
was added this need to be keep for backward compatibility.
While at it reduce the info structure bloat and reuse the Gen4 info
structure for V3U (R8A779A0), which is the last Gen3 board but that had
a completely new video capture design that is compatible with Gen4 VIN.

* Changes since v3
- Reworked to deal with a Gen4 family compatible instead of a V4M SoC
specific one.
- Dropped review tags.
* Changes since v2
- Extend commit message to explain why SoC specific compatibles are use
in the driver instead of adding a new Gen4 fallback to cover both V4H
and V4M.
- Add review tags.
* Changes since v1
- Create a shared Gen4 info strucutre.
