This is useful for easily adding SPI support in later patches.
Now bmc150_magn exports core functions to be used by I2C/SPI drivers
instances. For the moment only I2C driver is supported.

This patch moves hmc5843 driver from staging/iio/magnetometer
to iio/magnetometer, updates the corresponding Makefiles and
moves the hmc5843* entries to the 'Industrial I/O support ->
Magnetometer sensors' menu.

Sort the entry for bmc105_magn in Kconfig and Makefile to its correct
position. Also add the minor module information for completeness.

Add support for the Bosh BMC150 Magnetometer.
The specification can be downloaded from:
http://ae-bst.resource.bosch.com/media/products/dokumente/bmc150/BST-BMC150-DS000-04.pdf.
The chip contains both an accelerometer and a magnetometer.
This patch adds support only for the magnetometer part.
The temperature compensation formulas are based on bmm050_api.c

Add 2 new definition entries to support ak0991x compass.
Add a more advanced function to check we are dealing with the
expected device.
Remove standalone driver for ak09911.

Added IIO magnetometer driver for AK09911. In functionality is resembles
AK8975 or AK8963. But there are several differences, so instead of
modifying existing AK8975 driver and keep it clean, implemented as
a separate driver.
The key differences are:
- Register map is different and have different indexes
- AK09911 is a very compact interface with no DRDY pin. So no support
of interrupt or GPIO poll
- Even for polled mode no mention on ST2 register, which is required in
ak8975 driver
- mode values are different for fuse access

Keeping Makefile and Kconfig entries in alphabetical order usually works better
than just appending new entries at the end, since it reduces the amount of
conflicts. This patch adds a comment to the IIO Kconfig and Makefile files to
document that the entries should be kept in alphabetical order.
Also reorder those entries which weren't in alphabetical order yet.

Issues raised in last series to propose this have now been resolved

Added usage id processing for Compass 3D. This uses IIO
interfaces for triggered buffer to present data to user
mode.This uses HID sensor framework for registering callback
events from the sensor hub.
