First round of IIO new drivers, cleanups and functionality for the 3.20 cycle take 2

Updated pull request with Daniel's fix on top for the power management
Kconfig changes that had snuck in since last update of the IIO tree
worked it's way through from mainline.

Original pull message

New device support
* jsa1212 proxmity / ambient light sensor
* SM08500 supported added to the kxcjk-1013 accelerometer driver
* KMX61 Accelerometer/Magnetometer.  This took a somewhat rocky path
  being first merged, then reverted for a rewrite after a discussion of
  how to support additional functionality and finally being merged prior
  to some last reviews coming in, with resultant follow up patches.
* Freescale mma9551l driver (minor follow up warning supression patch).
* Semtech SX9500 proximity device driver.
* ak8975 gains support for ak09911 and ak09912 and drop the standalone driver
  for the ak09911.

New functionality
 * Dummy driver gains some virtual registers making it more flexible.
 * IIO_ACTIVITY channel types, with modifiers running, walking etc.  This is
   to support on chip motion clasifiers.  As such it is in the form of a
   confidence percentage.  The only devices so far only do binary decisions
   but this gives us room when other devices give more nuanced clasification.
 * IIO_EV_DIR_NONE type for events where there is no obvious direction.
   First case is step detection.
 * IIO_STEPS channel type for pedometers.
 * ENABLE mask element used to control turning on counting types such as
   the pedometer that need a 'start point'.
 * INSTANCE event type to support things that happen once.
 * info element for height calibration (used in various motion estimation
   algorithms). Note heigh tof use
 * dummy driver demonstration of the use of all the new bits above.
 * event monitor support for the new events.
 * inv_mpu6050 gains an i2c mux to allow bypassing the device to access
   additional devices connected on the other side of it.  Note that in
   Windows these are handled by firmware on the device and not exposed
   directly.
 * inv_mpu6050 gains ACPI enumeration.
 * inkern interface gains iio_write_channel_raw to allow in kernel users
   of DAC functionality via a simple wrapper.
 * Document input current readings in the ABI docs.
 * Add an error message when we get an out of range error in device tree
   processing for the in kernel interfaces.  Basically a device tree debugging
   aid.
 * Add a sanity check that a scan index for a channel is unique during
   registration.  There to help catch bugs as this should never happen
   in a bug free driver.

Cleanups and fixlets

 A rework of buffer registration from Lars - a precursor to some other
 upcoming new stuff (a few patches from others rolled in here as well).
 * Ensure all drivers register the same channels for the device and buffer.
 * Move buffer registration into the core rather than using the old
   two step approach.  Now we have simple ways of using a unified set channels
   for both without requiring channels be exposed by both interface, this
   removes a fair bit of boilerplate.
 * Stop sca3000 and ad5933 (both in staging) enabling buffer channels by
   default. It has long be convention in IIO to startup with no channels
   enabled and leave it up to userspace to say what goes in the buffer.
   Getting rid of these allows us to drop export of iio_scan_mask_set.
 * Drop get_bytes_per_datum from iio_buffer_access_funcs as not been used
   for a while.
 * Allocate standard buffer attributes in the core rather than in every
   driver with a buffer.
 * Make the length attribute read only when a driver is not able to set
   the length.
 * Drop the get_length callback for buffers as it is already available in
   struct iio_buffer.
 * Drop an unused arguement form iio_kfifo_allocate and add devm allocator
   for it.
 * some kconfig entries gain anotation with the resulting module name.
 * Fix a resulting compile issue in dummy driver due to a stub taking
   wrong parameters as a result of the above rework.
 * Fix an off by 2 error in copying the core assigned buffer attributes.

Other cleanups,
 * Trivial space before comma fixups.
 * ak8975 fixlets - none critical.  Rework to allow more device support.
 * Drop unnecessary sizeof(u8) calls.
 * bmp280 - refactor the compensation code to reduce copy operations and
   code length.  A second patch futher optimized this and performed some
   other minor cleanups.
 * kxcjk-1013 - various power control cleanups to avoid unnecessary enable
   / disable of device.  Make sure it is only controlled at all if CONFIG_PM
   is enabled.  Also som cleanups of error paths.
 * Small cleanups in adf4530 driver - pointless message and unnecessary braces.
 * Clarifiy the proximity ABI docs to make it clear it should get bigger
   as we move futher away.
 * Drop a misleading comment form industrialio-core.c
 * Trivial white space cleanups.
 * sca3000 looses an unused debug function.
 * Fix char unsigned ordering in ad8366
 * Increase the sleep time in ad9523 to make it predictable (value didn't
   really matter so make it more than 20 msecs)
 * mxs-lradc touchscreen property cleanups in device tree are fixed to ensure
   the meet all the 'interesting' documentation.
 * A couple of cleanups for the staging ad5933 driver to avoid unnecessary

staging: ion: always initialize the free list parameters

Currently we initialize the heap free_lock and free list size in
ion_heap_init_deferred_free, which is only called when the
ION_HEAP_FLAG_DEFER_FREE heap flag is given.  However, the lock and size
are used in the shrinker path as well as the deferred free path, and we
can register a shrinker *without* enabling deferred freeing.  So, if a
heap provides a shrinker but *doesn't* set the DEFER_FREE flag we will
use these parameters uninitialized (resulting in a spinlock bug and
broken shrinker accounting).

Fix these problems by initializing the free list parameters directly in
ion_device_add_heap, which is always called no matter which heap
features are being used.

Staging: wlan-ng: hfa384x_usb: fixed an 'else' statement coding style issue

Removed useless 'else' statement that followed an 'if' statement that
had a return 1 and moved all the content from the 'else' to outside of
the switch case, this way if any case is sufficient it returns '1',
otherwise it will return 0.
