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.
