media: Documentation: mali-c55: Use v4l2-isp version identifier

The Mali C55 driver uses the v4l2-isp framework, which defines its own
versioning numbers.

Do not use the Mali C55 specific version identifier in the code example
in the documentation of the Mali C55 stats and params metadata formats.
