doc_rst: rename the media Sphinx suff to Documentation/media

The name of the subsystem is "media", and not "linux_tv". Also,
as we plan to add other stuff there in the future, let's
rename also the media uAPI book to media_uapi, to make it
clearer.

No functional changes.

+    :header-rows:  0
+    :stub-columns: 0
+
+
+    -  .. row 1
+
+       -  int fd
+
+       -  File descriptor returned by a previous call to open().
+
+    -  .. row 2
+
+       -  int request
+
+       -  Equals DMX_SET_FILTER for this command.

+       -  struct dmx_sct_filter_params \*params
+
+       -  Pointer to structure containing filter parameters.
+
+
+Description
+-----------
+
+This ioctl call sets up a filter according to the filter and mask
+parameters provided. A timeout may be defined stating number of seconds
+to wait for a section to be loaded. A value of 0 means that no timeout
+should be applied. Finally there is a flag field where it is possible to
+state whether a section should be CRC-checked, whether the filter should
+be a ”one-shot” filter, i.e. if the filtering operation should be
+stopped after the first section is received, and whether the filtering
+operation should be started immediately (without waiting for a
+DMX_START ioctl call). If a filter was previously set-up, this filter
+will be canceled, and the receive buffer will be flushed.
+
+
+Return Value
+------------
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
