First set of new device support, features and cleanups for IIO in the 5.11 cycle

Usual mixed bag of new drivers / device support + cleanups etc with the
addition of a fairly big set of yaml conversions.

Txt to yaml format conversions.
In some cases dropped separate binding and moved to trivial devices (drop).

New device support
* adi,ad5685
  - Add support for AD5338R dual output 10-bit DAC
  - Add DT-binding doc.
* mediatek,mt6360
  - New driver for this SoC ADC with bindings and using new channel label
    support in the IIO core.
* st,lsm6dsx
  - Add support for LSM6DST

Core:
* Add "label" to device channels, provided via a new core callback. Including
  DT docs for when that is the source, and ABI docs.
* Add devm_iio_triggered_buffer_setup_ext to take extra attributes.
* dmaengine, unwrap use of iio_buffer_set_attrs()
* Drop iio_buffer_set_attrs()
* Centralize ioctl call handling. Later fix to ensure -EINVAL returned if
  no handler has run.
* Fix an issue with IIO_VAL_FRACTIONAL and negative values - doesn't affect
  any known existing drivers, but will impact a future one.
* kernel-doc fix in trigger.h
* file-ops ordering cleanup

Features
* semtech,sx9310
  - Add control of hardware gain, proximity thresholds, hysteresis and
    debounce.
  - Increase what information on hardware configuration can be provided
    via DT.

Cleanup and minor features
* adi,ad5685
  - Add of_match_table
* adi,ad7292
  - Drop pointless spi_set_drvdata() call
* adi,ad7298
  - Drop platform data and tidy up external reference config.
* adi,ad7303
  - Drop platform data handling as unused.
* adi,ad7768
  - Add new label attribute for channels provided from dt.
* adi,ad7887
  - devm_ usage in probe simplifying remove and error handling.
* adi,adis16201
  - Drop pointless spi_set_drvdata() call
* adi,adis16209
  - Drop pointless spi_set_drvdata() call
* adi,adis16240
  - White space fixup
* adi,adxl372
  - use new devm_iio_triggered-buffer_setup_ext()
* amlogic,meson-saradc
  - Drop pointless semicolon.
* amstaos,tsl2563
  - Put back i2c_device_id table as needed for greybus probing.
* atmel,at91_adc
  - Use of_device_get_match_data() instead of open coding it.
  - Constify some driver data
  - Add KCONFIG dep on CONFIG_OF and drop of_match_ptr()
  - Drop platform data as mostly dead code.
  - Tidy up reference voltage logic
* atmel-sama5d2
  - Drop a pointless semicolon
  - Merge buffer and trigger init into a separate function
  - Use new devm_iio_triggered_buff_setup_ext()
* avago,apds9960
  - Drop a pointless semicolon
* bosch,bmc150
  - Drop a pointless semicolon
  - Use new iio_triggered_buffer_setup_ext()
* bosch,bmp280
  - Drop a pointless semicolon
* fsl,mma8452
  - Constification
* (google),cros_ec
  - Use new devm_iio_triggered_buffer_setup_ext()
* hid-sensors
  - Use new iio_triggered_buffer_setup_ext()
* ingenic,adc
  - Drop a pointless semicolon
* invensense,icm426xx
  - Fix MAINTAINERS entry missing :
* mediatek,mt6577_audxac
  - Add binding doc for mt8516 compatible with mt8173
* motorola,cpcap-adc
  - Fix an implicit fallthrough marking that clang needs to avoid warning.
* samsung,exynos-adc
  - Stop relying on users counter form input device in ISR.
* st,lsm6dsx
  - add vdd and vddio regulator control (including binding update)
* st,stm32-adc
  - Tidy up code for dma transfers.
  - Adapt clock duty cycle for proper functioning. Note no known problems
    with existing boards.
* st,vl53l0x-i2c
  - Put back i2c_device_id table as needed for greybus probing.
* vishay,vcnl4035
  - Put back i2c_device_id table as needed for greybus probing.
