media: docs: move uAPI book to userspace-api/media

Since 2017, there is an space reserved for userspace API,
created by changeset 1d596dee3862 ("docs: Create a user-space API guide").

As the media subsystem was one of the first subsystems to use
Sphinx, until this patch, we were keeping things on a separate
place.

Let's just use the new location, as having all uAPI altogether
will likely make things easier for developers.

-LIRC_SET_TRANSMITTER_MASK - Enables send codes on a given set of transmitters
-
-Synopsis
-========
-
-.. c:function:: int ioctl( int fd, LIRC_SET_TRANSMITTER_MASK, __u32 *mask )
-    :name: LIRC_SET_TRANSMITTER_MASK
-
-Arguments
-=========
-
-``fd``
-    File descriptor returned by open().
-
-``mask``
-    Mask with channels to enable tx. Channel 0 is the least significant bit.
-
-
-Description
-===========
-
-Some IR TX devices have multiple output channels, in such case,
-:ref:`LIRC_CAN_SET_TRANSMITTER_MASK <LIRC-CAN-SET-TRANSMITTER-MASK>` is
-returned via :ref:`LIRC_GET_FEATURES` and this ioctl sets what channels will
-send IR codes.
-
-This ioctl enables the given set of transmitters. The first transmitter is
-encoded by the least significant bit and so on.
-
-When an invalid bit mask is given, i.e. a bit is set, even though the device
-does not have so many transitters, then this ioctl returns the number of
-available transitters and does nothing otherwise.
-
-
-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.
