Hi Eugen

VIDIOC_ENUM_FRAMEINTERVALS is not recommended for a top video driver.
The frame rate is defined by the sensor subdevice, thus it can be queried
directly by anyone interested in the frame intervals.
This change makes sense in the context of moving towards media
controller, but I wonder how does this impact existing userspace that
relies on this.

Anyway
