The MAX96712 and MAX96724 are both quad GMSL2 to CSI-2 deserializers and
are in parts similar, but not identical. The most obvious difference is
on the CSI-2 side where the MAX96712 have 4 PHYs and support D-PHY with
1x4, 2x2 and 4x2 lanes where the MAX96724 only have 2 PHYs and supports
D-PHY with 2x4 or 4x2 lanes.
The register layout overlap in part but there are differences and holes.
Most of the differences are related to the different number of CSI-2
PHYs, but there are other capability differences between the two.
Add a specific compatible for MAX96724 to the max96712 bindings. The
bindings do not yet support validating all DT properties to limit it the
each devices capabilities. However to allow for this in future a
specific compatible for the two different devices are needed.

* Changes since v2
- Expand on the differences of the two devices and why a specific
binding is needed for the new device.
* Changes since v1
- Group in series together with driver change.
