Subject: [PATCH] media: dt-bindings: Add OminiVision 0V02C10

Extend the ov02e10 bindings yaml to describe the ov02c10 sensor which has
the same bindings with a different compat string and different i2c
address only.

Other differences in sensor capabilities exist but are not expressed in
devicetree.

I previously submitted a standalone ov02c10 yaml file but, it was pointed
out to me by Krzysztof that the ov02e10 yaml has exactly the same bindings
and we should therefore extend the ov02e10 yaml.

Link: https://lore.kernel.org/linux-media/da93bf6c-b4bc-4c4f-9373-583fbd0c031c@kernel.org/

The accompanying patch:

- Updates the overall description to differentiate between the two sensors
- Adds ovti,ov02c10 compat string
- Adds an example for the ov02c10

Once merged we can also merge the ov02c10 driver, which contains a compat
string requiring yaml description as precursor to merge.
