The code and documentation are more difficult to maintain when kept
separately. This is further compounded when the standard structure
documentation infrastructure is not used.
Move the documentation into the code, use the standard documentation
infrastructure, add current documented functions, and reference the text
in the rst file.

Add an example code snipit to the module_auxiliary_driver()
documentation which is consistent with the other example code in the
elsewhere in the documentation.

For some reason, the original aux bus patch had some really long lines
in a few places, probably due to it being a very long-lived patch in
development by many different people. Fix that up so that the two files
all have the same length lines and function formatting styles.

There's an effort to move the remove() callback in the driver core to
not return an int, as nothing can be done if this function fails. To
make that effort easier, make the aux bus remove function void to start
with so that no users have to be changed sometime in the future.

No need to include slab.h in include/linux/auxiliary_bus.h, as it is not
needed there. Move it to drivers/base/auxiliary.c instead.

Add support for the Auxiliary Bus, auxiliary_device and auxiliary_driver.
It enables drivers to create an auxiliary_device and bind an
auxiliary_driver to it.
The bus supports probe/remove shutdown and suspend/resume callbacks.
Each auxiliary_device has a unique string based id; driver binds to
an auxiliary_device based on this id through the bus.
