First round of new features, device support and cleanups for IIO in the 4.9 cycle.

Device support

* ak8974
  - New driver and bindings for this 2009 vintage magnetometer (it was very
    popular back then!)
* atlas-ph-sensor
  -  ORP sensor support(I had to look up what one of these was)
* cio-dac
  - New driver for Measurement Computing DAC boards
* dmard06
  - New driver for Domintech DMARDO6 accelerometer. Also vendor prefix.
* dmard09
  - New driver for Domintech DMARD09 accelerometer.
* maxim-thermocouple
  - max6675 and max31855 new driver
* mt6577 auxdac
  - new driver for this Mediatek chip mt2701, mt6577 and mt8173 have this
    hardware.
* ti-adc161s626
  - new driver for this TI single channel differential ADC.
* vcnl4000
  - support vcnl4010 and vcnl4020 which are compatible for all features
    currently supported by this driver.

New features

* Core
  - Allow retrieving of underlying iio_dev from a callback buffer handle.
    This is needed to allow client drivers to perform operations such as
    configuring the trigger used.
* hid-sensors
  - asynchronous resume support to avoid really long resume times.
* kxcjk-1013
  - add the mysterious KIOX000A ACPI id seen in the wild.
* Tools
  - lsiio now enumerates processed as well as raw channels.

Cleanup

* ad7298
  - use iio_device_claim_direct_mode and friends to simplify locking around
    mode switching and drop some boilerplate.
* ad7793
  - use iio_device_claim_direct_mode and friends to simplify locking around
    mode switching and drop some boilerplate.
* ade7854
  - checkpatch fixups (alignment of parameters)
* atlas-ph-sensor
  - use iio_device_claim_direct_mode and friends to simplify locking around
    mode switching and drop some boilerplate.
  - Switch to REGCACHE_NONE as there are no useful register to cache.
* bma180
  - use iio_device_claim_direct_mode and friends to simplify locking around
    mode switching and drop some boilerplate.
* hdc100x
  - Add mention of the HDC1000 and HDC1008 to the Kconfig help text.
* isl29018
  - Add driver specific prefixes to defines and function names.
  - Remove excessive logging.
  - Drop newlines which add nothing to readability.
  - General tidying up of comments.
  - Drop I2C_CLASS_HWMON as irrelevant to driver.
* isl29028
  - Add driver specific prefixes to defines, enums and function names.
  - Drop comma's from available attribute output as not ABI compliant.
  - Drop I2C_CLASS_HWMON as irrelevant to driver.
* kxsd9
  - devicetree bindings.
* mag3110
  - This one wasn't locking to protect against mode switches during
    raw_reads.  Use the iio_claim_direct_mode function to fix this buglet.
* maxim-theromcouple
  - Fix missing selects for triggered buffer support in Kconfig.
* nau7802
  - Use complete instead of complete_all as only one completion at a time.
* sx9500
  - Use complete instead of complete_all as only one completion at a time.
* us5182d
  - Add a missing error code asignment instead of checking the result of
    an already checked statement.
* vcnl4000
  - Use BIT macro where appropriate.
  - Refactor return codes in read_raw callback.
  - Add some missing locking for concurrent accesses to the device.
