Second round of IIO new drivers, functionality and cleanups for the 3.20 cycle.

New drivers and device support:
* Capella cm3232 ambient light sensor driver.
* Freescale MMA9553 pedometer and activity monitor. Note this involved a
  refactor of the mma9551 driver to pull out shared elements.
* Samsung sensor hub (as used in the galaxy gear 2 watch) Core support
  and initial drivers (gyro and accelerometer) more to follow.
  An additional fix was applied on top of this for a build issue
  thrown up by the autobuilders on some platforms.
* Cosmic Circuits 10001 ADC driver
* Qualcomm SPMI PMIC voltage ADC driver (current adc merged a while back).
* Add binding for AK8963 (in capitals) as unfortunately there are bios'
  out there not using lower case.

New functionality
* Add newe operating mode to the core to allow for non triggered software
  buffers.  This is mostly semantics as previously drivers just claimed they
  had a hardware buffer (when they didn't).
* Add distance channel type.
* Add energy channel type.
* Add velocity channel type and IIO_MOD_ROOT_SUM_SQUARED (i.e. speed when
  our channel type is velocity).
* Add _debounce_count and _debounce_time filter attributes.  Only really
  make sense for counting types of measurements.  First use is for avoiding
  miss detection of steps prior to walking.
* Add change event type.   This replaces the briefly present INSTANCE type
  (which hadn't gained any users).  It is more generic as it allows for
  events say every 10 steps rather than every step.
* Add _calibweight attributes to the ABI (and core support).  Used by
  activity monitors to estimate energy use.  Can imagine there will be
  other uses for this one.

Driver new functionality
* mma9551 gains runtime pm support.
* hid-sensors gain PM support.

Cleanup
* Change calibheight unit to m from cm.  As there are no prior users
  and this was inconsistent with other distance units, it makes sense
  to fix it before hte mma9553 driver which uses it.
* mpu6050 cleanups and devm_ use.
* as3935 switch over to PM ops.
* Fix a few format strings for signed vs unsigned.
* Fix tcs3414 missindentation
* Typo in industrialio-event
* Stop requiring IIO_TRIGGER for IIO_KFIFO_BUF as we have drivers that don't
  need it. No one is quite sure why that dependency was there and it
  seems to not matter.
