[yocto] Layer documentation for meta-raspberrypi

[Paul Barker]

Hi all,

As a quick announcement, the layer documentation for meta-raspberrypi
is now available on Read the Docs:
http://meta-raspberrypi.readthedocs.io/en/latest/

The latest documentation is shown by default and covers the master
branch. Using the version box in the bottom right corner of the page
you can also switch to the rocko or pyro versions. This is
automatically updated whenever changes are pushed to the documentation
in meta-raspberrypi.

Raspberry Pi seems to be a very common platform for newcomers to
OE/Yocto and so I think it's really important that this layer is well
documented and is easy to use. Please submit pull requests or open
bugs if you think any of the documentation can be improved.

We use Sphinx (http://www.sphinx-doc.org/) plus Read the Docs
(https://readthedocs.org/) integration for this which I think is a
pretty good setup for layer documentation in general. If anyone wants
more details so they can do something similar for another layer then
please let me know!

Cheers,
