Second round of new iio device support, features and cleanups in the 4.8 cycle

Firstly some contact detail updates:
* NXP took over freescale. Update the mma8452 header to reflect this.
* Martin Kepplinger email address change in mma8452 header.
* Adriana Reus has changed email address. Update .mailmap.
* Matt Ranostay has changed email address. Update .mailmap.

New Device Support
* max1363
  - add the missing i2c_device_ids for a couple of parts so they can actually
    be used.
* ms5867
  - add device ids for ms5805 and ms5837 parts.

New Features
* ad5755
  - DT support.  This one was a bit controversial and under review for a long
    time.  Still no one could come up with a better solution.
* stx104
  - add gpio support
* ti-adc081c
  - Add ACPI device ID matching.

Core changes
* Refuse to register triggers with duplicate names.  There is no way to
  distinguish between them so this makes no sense.  A few drivers do not
  generate unique names for each instance of the device present.  We can't
  fix this without changing ABI so leave them and wait for someone to
  actually take the rare step of two identical accelerometers on the same
  board.
* buffer-dma
  - use ARRAY_SIZE in a few appropriate locations.

Tools
* Fix the fact that the --trigger-num option in generic_buffer didn't allow
  0 which is perfectly valid in the ABI.

Cleanups
* as3935
  - improve error reporting.
  - remove redundant zeroing of a field in iio_priv.
* gp2ap020a00f
  - use the iio_device_claim_*_mode helpers rather than open coding locking
  around mode changes.
* isl29125
  - use the iio_device_claim_*_mode helpers rather than open coding locking.
* lidar
  - use the iio_device_claim_*_mode helpers rather than open coding locking.
* mma8452
  - more detail in devices supported description in comments (addresses and
  similar)
* sca3000
  - add a missing error check.
* tcs3414
  - use the iio_device_claim_*_mode helpers rather than open coding locking.
* tcs3472
  - use the iio_device_claim_*_mode helpers rather than open coding locking.
