Mauro Carvalho Chehab d6b6d346e5 [media] DocBook: better document FE_SET_VOLTAGE ioctl
Use the proper format for FE_SET_VOLTAGE documentation and fix
the documentation. The description for the enum is not 100%,
and it is missing the voltage off value.

Also, it is better to keep the enum description together with
the ioctl, as both are used together.

Mauro Carvalho Chehab 55d4423a2d [media] DocBook: Fix false positive undefined ioctl references
The new code that detects undocumented ioctls hits some false
positives:

This one is not documented, nor it should, as this is
there just to reserve namespace:

	Warning: can't find reference for VIDIOC_RESERVED ioctl

But those are already documented together with other ioctls:

	Warning: can't find reference for VIDIOC_UNSUBSCRIBE_EVENT ioctl
	Warning: can't find reference for FE_GET_PROPERTY ioctl
	Warning: can't find reference for VIDIOC_SUBDEV_G_EDID ioctl
	Warning: can't find reference for VIDIOC_SUBDEV_S_EDID ioctl
	Warning: can't find reference for VIDIOC_SUBDEV_S_DV_TIMINGS ioctl
	Warning: can't find reference for VIDIOC_SUBDEV_G_DV_TIMINGS ioctl
	Warning: can't find reference for VIDIOC_SUBDEV_QUERY_DV_TIMINGS ioctl

So, we need to just be sure to point to the right documentation.

The DVB part of the docbook has a completely different format

this source has not been updated because it is broken since the very
