[libcamera-devel] [PATCH v2] libcamera: controls: Drop reference to IPA in controls documentation

[Laurent Pinchart]

The controls relates to the public API, which doesn't expose IPA modules
as they are internal to libcamera. Replace the mention of "IPA" in the
controls documentation.

While at it, fix a small text reflow issue.
