doc-rst: Remove the media docbook
Now that all media documentation was converted to Sphinx, we should get rid of the old DocBook one, as we don't want people to submit patches against the old stuff.

- <title>Description</title>
- <para>To query the attributes of an entity, applications set the id field
- of a &media-entity-desc; structure and call the MEDIA_IOC_ENUM_ENTITIES
- ioctl with a pointer to this structure. The driver fills the rest of the
- structure or returns an &EINVAL; when the id is invalid.</para>
- <para>Entities can be enumerated by or'ing the id with the
- <constant>MEDIA_ENT_ID_FLAG_NEXT</constant> flag. The driver will return
- information about the entity with the smallest id strictly larger than the
- requested one ('next entity'), or the &EINVAL; if there is none.</para>
- <para>Entity IDs can be non-contiguous. Applications must
- <emphasis>not</emphasis> try to enumerate entities by calling
- MEDIA_IOC_ENUM_ENTITIES with increasing id's until they get an error.</para>
