Second set of new drivers, functionality and cleanups for IIO in the 4.4 cycle.

Core stuff
* adjust resistance documentation to allow for output devices.

New device support:
* bmc150
 - split the i2c driver up into a core and i2c_regmap part including regmap
   conversion.
 - add spi support.
* mcp4531 digitial potentiometer driver.
* Measurement Specialties set of drivers with a core library module providing
  common functionality.  Note that the htu21 has a driver in hwmon, but the
  view from that side was that, given the range of devices the same silicon
  turns up in are not all typical hwmon material, that driver would be
  deprecated in favour of this new support.
 - ms8607 temperature, pressure and humidty sensor
 - ms5637 temperature and pressure sensor
 - htu21 temperature and humidity sensor
 - tsys02d temperature sensor
 - tsys01 temperature sensor

Cleanups
* tree wide.
 - squish cases where irq 0 is still considered valid.
* apds9960
 - sparse endian warning cleanups by making endianness explicit.
* ad5504
 - leave group naming to the core.
* ad7746
 - cleanup comment style.
 - drop an unnecessary bit of dev_info
 - add some appropriate uses of the BIT macro.
* ad799x
 - leave group naming to the core.
* hdc100x - introduced this cycle,.
 - fix a wrong offset value.
* lidar
 - add missing MODULE_DEVICE_TABLE for dt.
* max1363
 - leave sysfs group naming to the core.
* m62332 got the Harmut treatment and as ever he found a 'few' bits the
  rest of us had missed!
 - Share scale and offset attributes across channels.
 - Shutdown the device on driver remove
 - Use ARRAY_SIZE rather than a hard coded count for channels.
 - Return more directly in the write_raw callback dropping a local variable
   along the way.
 - a few style issues
 - move to reading the regulator voltage for each use allowing for dynamic
   regulators.  This is a common feature across drivers so we might end
   up with more fixes throughout the tree for this.
* mlx96014 - introduced this cycle.
 - fixed up a spot of error handling.
* vz89x - introduced this cycle.
 - work around a hardware quirk.
