Documentation/devices.rst: convert it to ReST markup 

- use a quote block for the big device major/minor list;
- use tables for the other device tables;
- fix the chapter/section/subsection markups;
- use ``foo`` for monotonic;
- use .. attention:: for the attention note to developers;
- use cross-references where needed;
- cleanup whitespaces;
- add it to the user's book.

LINUX ALLOCATED DEVICES (4.x+ version)
Linux allocated devices (4.x+ version)
======================================
This list is the Linux Device List, the official registry of allocated
device numbers and /dev directory nodes for the Linux operating
device numbers and ``/dev`` directory nodes for the Linux operating
system.
The LaTeX version of this document is no longer maintained, nor is
the document that used to reside at lanana.org. This version in the
mainline Linux kernel is the master document. Updates shall be sent
as patches to the kernel maintainers (see the SubmittingPatches document).

:ref:`Documentation/SubmittingPatches <submittingpatches>` document).
Specifically explore the sections titled "CHAR and MISC DRIVERS", and
"BLOCK LAYER" in the MAINTAINERS file to find the right maintainers
to involve for character and block devices.

.. attention::
Linux now has extensive support for dynamic allocation of device numbering
and can use sysfs and udev (systemd) to handle the naming needs. There are
still some exceptions in the serial and boot device area. Before asking
for a device number make sure you actually need one.
DEVICE DRIVERS AUTHORS PLEASE READ THIS
To have a major number allocated, or a minor number in situations
where that applies (e.g. busmice), please submit a patch and send to
the authors as indicated above.

Keep the description of the device *in the same format
as this list*. The reason for this is that it is the only way we have
found to ensure we have all the requisite information to publish your
device and avoid conflicts.

Finally, sometimes we have to play "namespace police." Please don't be
offended. We often get submissions for /dev names that would be bound
to cause conflicts down the road. We are trying to avoid getting in a
situation where we would have to suffer an incompatible forward
change. Therefore, please consult with us *before* you make your
device names and numbers in any way public, at least to the point
where it would be at all difficult to get them changed.

Serial ports are RS-232 serial ports and any device which simulates
