[PATCH 5/5] media: uapi: move H264 stateless controls out of staging

[Ezequiel Garcia <ezequiel@xxxxxxxxxxxxx>]

The H264 stateless control class is ready to be part
of the stable uAPI.

The control IDs and types are re-numbered and moved
to a newly created stateless control class, and
a new documentation section is created.

+Stateless Codec Control Reference
+*********************************
+
+The Stateless Codec control class is intended to support
+stateless decoder and encoders (i.e. hardware accelerators).
+
+These drivers are typically supported by the :ref:`stateless_decoder`,
+and deal with parsed pixel formats such as V4L2_PIX_FMT_H264_SLICE.
