Documentation for irmc hardware type

Added documentation for irmc hardware type. Also added
some anchors into enabling-drivers.rst due to the current
doc needs to refer to some parts of that one.

+Hardware Type
+=============
+
+The ``irmc`` hardware type is introduced to support the new Ironic driver
+model. It is recommended to use ``irmc`` hardware type for FUJITSU PRIMERGY
+hardware instead of the classic drivers.
+
+For how to enable ``irmc`` hardware type, see :ref:`enable-hardware-types`.
+
+Hardware interfaces
+^^^^^^^^^^^^^^^^^^^
+
+The ``irmc`` hardware type overrides the selection of the following
+hardware interfaces:
+
+* boot
+    Supports ``irmc-virtual-media``, ``irmc-pxe``, and ``pxe``.
+    The default is ``irmc-virtual-media``.
+
+    .. warning::
+       We deprecated the ``pxe`` boot interface when used with ``irmc``
+       hardware type. Support for this interface will be removed in the
+       future. Instead, use ``irmc-pxe``. ``irmc-pxe`` boot interface
+       was introduced in Pike and is used in the ``pxe_irmc`` classic
+       driver.
+
+* console
+    Supports ``ipmitool-socat``, ``ipmitool-shellinabox``, and ``no-console``.
+    The default is ``ipmitool-socat``.
+
+* inspect
+    Supports ``irmc``, ``inspector``, and ``no-inspect``.
+    The default is ``irmc``.
+
+    .. note::
+       `Ironic Inspector <https://docs.openstack.org/ironic-inspector/latest/>`_
+       needs to be present and configured to use ``inspector`` as the
+       inspect interface.
+
+* management
+    Supports only ``irmc``.
+
+* power
+    Supports only ``irmc``.
+
+For other hardware interfaces, ``irmc`` hardware type supports the
+Bare Metal reference interfaces. For more details about the hardware
+interfaces and how to enable the desired ones, see
+:ref:`enable-hardware-interfaces`.
+
+Here is a complete configuration example with most of the supported hardware
+interfaces enabled for ``irmc`` hardware type.

+Upgrading to ``irmc`` hardware type
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+When upgrading from a classic driver to the ``irmc`` hardware type,
+make sure you specify the hardware interfaces that are used by the
+classic driver. :doc:`/admin/upgrade-to-hardware-types` has more
+information, including the hardware interfaces corresponding to
+the classic drivers.
