DocBook media: fix VIDIOC_CROPCAP type description
Subsystems (2)
The type field of VIDIOC_CROPCAP does not allow the MPLANE variants, just as all the other crop/selection related ioctls.
Fix the description of CROPCAP and G_CROP and make the text describing this consistent for all selection ioctls.
