Second set of new device support, features and minor fixes for IIO in the 5.6 cycle

Just a small set this time.

As we are very near the merge window, I've rolled a few fixes in here
rather than adding noise just before release.  A short delay here will
do little harm.

New device support
* adis16480
  - Add support for adis16490. After earlier rework this is simple ID plus
    chip info.

Features
* kxcjk1013
  - mount matrix support.
* lsm_6dsx
  - mount matrix support.

Cleanups / minor or late breaking fixes
* ad7124
  - add support to ad-sigma-delta and use it in this driver to allow
    the the interrupt type to be IRQF_TRIGGER_LOW unlike most other devices
    using this framework.
* adis
  - use delay structure now available in SPI to handle transfer delays
  - introduce a timeouts structure to allow support of new devices
* ak8975
  - drop platform data support.  No one is using it and it adds complexity.
  - use device_get_match_data rather than open coding much the same thing.
* dht11
  - drop meaningless todo
* at91-samad2_adc
  - switch to dma_request_chan
* altas-sensor
  - add a helper function to compute number of channels.  Needed for new device
    support that is under review.
* bma400
  - add a lower bound check on scale.
* inv_mpu6050
  - add support for temperature data in the fifos for all chips.
  - support an odd situation where a board supports only interrupt triggering
    on both edges.
* st_lsm6dsx
  - check and handle potential error return.
* st_sensors
  - fix some values for the LSM9DS0 which is ever so slightly different from
    other devices using the same whoami value.
  - switch over to generic functions from dt ones, avoiding need for separate
    ACPI support.
* stm32-adc
  - switch to dma_request_chan
  - suppress an error print in deferred probe case.
* stm32-dac
  - drop private data structure element for reset controller as only used in
    probe.
  - reflect more cleanly that the reset controller is optional whilst ensuring
    that if is specified any errors are caught.
* stm32-dfsdm
  - switch to dma_request_chan
  - fix missing application of formatting to single conversions.
  - ensure the sampling rate is updated when the oversampling ratio is changed.
