First round of IIO new device support, features and cleanups for the 4.7 cycle.

New core support
* UV light modifier (for intensity)
* UV light index channel type.

New device support
* hp206c barometer and altimeter
  - new driver.
* mcp4131 potentiometer
  - new driver supporting lots of parts from Microchip.
* mma8452
  - FXLS8471Q support
- NXP LPC18XX SOC ADC
  - new driver.
- NXP LPC18XX SOC DAC
  - new driver.
- rockchip_saradc
  - support rk3399
* st accel
  - h3lis331dl support

Staging driver removals
* adis16204
  - obsolete part making it hard to get parts to test the driver in order
    to clean it up.
* adis16220
  - obsolete part making it hard to get the parts test the driver in order
    to clean it up.

Features
* core
  - convenience functions to claim / release direct access to the device.
    Makes more consistent handling of this corner easier. Used in ad7192 driver.
* ak8975
  - power regulator support.
* at91-sama5d2
  - differential channel support.
* mma8452
  - runtime pm support
  - drop device specific autosleep and use the runtime pm one instead.
* ms5611
  - DT bindings
  - oversampling ratio support

Cleanups and minor fixes
* MAINTAINERS
  - Peter got married - hence name change!

* Documentation
  - Fix a typo in in_proximity_raw description.
  - Add some missing docs for iio_buffer_access_funcs.

* Tools
  - update iio_event_monitor names to match new stuff.
  - make generic_buffer look for triggers ending in -trigger as we let these in
  for a number of drivers a long time back and now it is a fairly common
  option.

Drivers
* staging wide
  - convert bare unsigned usage to unsigned int to comply with coding style.
* non staging wide:
  - since boiler plate gpio handling of interrupts has been moved into the
   ACPI core we don't need to include gpio/consumer.h in a load of drivers so
   drop it.
* ad7606
  - fix an endian casting sparse warning.
* ak8975
  - fix a possible unitialized warning from gcc.
  - drop and unused field left over from earlier cleanups
  - fix a missing regulator_disable on exit.
* at91-sama5d2
  - typo and indentation
  - missing IOMEM dependency.
  - cleanup mode register usage by avoidling erasing whole thing when changing
  the sampling frequency.
* bmc150
  - use the core demux and available_scan_masks to simplify buffer handling
  - optimize the transfers in the trigger handler now we have a magic function
  to emulate bulk reads (under circumstances met here).  This matters with some
  rather dumb i2c adapters in particular.
  - use a single regmap_conf for all bus types as they were all the same.
* bmg160
  - use the core demux and available_scan_masks to simplify the buffer handling
  - optimize the transfers in the trigger handler now we have a magic funciton
  to emulate bulk rads (under circumstances met here).
  - drop gpio interrupt probing from the driver (ACPI) as now handled by the
  ACPI core.
* ina2xx-adc
  - update the CALIB register when RShunt changes.
  - fix scale for VShunt - in reality this error canceled out when used.
* isl29028
  - use regmap to retrieve the struct device instead of carrying a second
  copy of it around.
* kxcjk-1013
  - use core demux
  - optimize i2c transfers in the trigger handler.
* mcp4531
  - refactor to use a pointer to access model parameters instead of indexing
    into the array each time.
* mma8452
  - style fixes
  - avoid swtiching to active whenever the config changes
  - add missin i2c_device_id for mma8451
* mpu6050
  - fix possible NULL dereference.
  - fix the name / chip_id used when ACPI used (otherwise reports as NULL).
* ms5611
  - fix a missing regulator_disable that left the regulator on during removal.
* mxc4005
  - drop gpio interrupt handling for ACPI case from driver as the core now
  handles this case.
* st-sensors
  - note that there are only ever a maximum of 3 axis on current st-sensors
  so just allocate a fixed sized buffer big enough for that.
* tpl0102
  - change the i2c_check_functionality condition to bring it inline with other
    IIO users as EOPNOTSUPP.
* tsl2563
  - replace deprecated flush_scheduled_work
