staging-specs: Add a staging tree for Documentation/DocBook
From: Mauro Carvalho Chehab <mchehab@redhat.com>
This patch basically copies V4L and DVB DocBook specs into a single file,
under a temporary staging tree. This is meant to add the set of V4L/DVB API
specifications at Linux Kernel.
For now, it just renames the *sgml files to *xml and creates a common body
for both API's, dividing them into two parts.
Later patches will add some glue for the two specs, move IR to a common part
(since IR keycodes are common to both API's) and add it into
linux/Documentation/DocBook.
Comments and reviews are welcome.
Priority: normal
