For patches 098 to 105, we should at least have those new controls
documented at the uAPI documents.

I'm not convinced yet that we shouldn't instead place them inside
V4L2_CTRL_CLASS_CAMERA.

As those are part of a MIPI standard, I won't doubt that sooner or
later, other drivers may need them.

Regards,
Mauro
