[media] doc-rst: document LIRC set mode ioctls

Add LIRC_SET_[REC|SEND]_MODE ioctls to the corresponding
GET functions, and put all LIRC modes altogether.

As now everything is already documented on its own ioctl
pages, get rid of lirc_ioctl.rst.

-LIRC ioctl - Sends a I/O control command to a LIRC device
-
-Synopsis
-========
-
-.. cpp:function:: int ioctl( int fd, int request, struct v4l2_capability *argp )
-
-
-Arguments
-=========
-
-``fd``
-    File descriptor returned by ``open()``.
-
-``request``
-    The type of I/O control that will be used. See table :ref:`lirc-request`
-    for details.
-
-``argp``
-    Arguments for the I/O control. They're specific to each request.
-
-
-The LIRC device's ioctl definition is bound by the ioctl function
-definition of struct file_operations, leaving us with an unsigned int
-for the ioctl command and an unsigned long for the arg. For the purposes
-of ioctl portability across 32-bit and 64-bit, these values are capped
-to their 32-bit sizes.
-
-The ioctls can be used to change specific hardware settings.
-In general each driver should have a default set of settings. The driver
-implementation is expected to re-apply the default settings when the
-device is closed by user-space, so that every application opening the
-device can rely on working with the default settings initially.
-
-.. _lirc-request:
-
-.. _LIRC_SET_SEND_MODE:
-.. _LIRC_SET_REC_MODE:
-
-``LIRC_SET_{SEND,REC}_MODE``
-
-    Set send/receive mode. Largely obsolete for send, as only
-    ``LIRC_MODE_PULSE`` is supported.
-
-.. _lirc_dev_errors:
-
-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.
