2nd set of IIO new device support, cleanups etc for 6.2

Includes a few late breaking fixes for old issues.

Contains a large set of conversions from i2c probe() to probe_new()
as part of an attempt to finally get rid of the old style probe().

New devices support
* adi,ad74115
  - New driver for this complex input/output device with 16 bit ADCs,
    14 bit DACs amongst other features.
  - A few tidy ups / removal of unused data patches followed.
* adi,adf4377
  - New driver for this dual output integer-N phased locked loop and VCO
    chip.
* maxim,max30208
  - New driver for this high accuracy digital temperature sensor.
* st,lsm6dsx
  - Support for LSM6DS016IS (chip specific data)
  - Support for ISM330IS (id entry only)

Minor cleanups etc
* adi,adis
  - Fix a deadlock on device instance specific mutex.
  - Tidy up by calling unlocked form of __adis_initial_startup() in all
    cases and dropping the locked version.
* adi,ad4130
  - Reference spi-peripehral-props.yaml in the dt-binding.
* adi,ad74413r
  - Fix a bug brought on by integer promotion of signed value to unsigned type.
  - Add an spi_device_id table to allow module autoloading to work.
  - Add support for reset pin.
* adi,ad7606_par
  - devm_platform_get_and_ioremap_resource() instead of opencoding.
* adi,ad7923
  - Add dt-bindings docs for ad7927 via a fallback to ad7928 and do similar
    for ad7924.
* adi,ltc2983
  - Drop a now unneeded $ref for -nanoamp property as dt-schema no covers this
    unit.
* maxim,max11410
  - Fix mask due to repeated use of VREFN instead of one of them being VREFP.
* qcom,spmi-iadc
  - Add fallback compatibles to dt-binding.
* renesas,rzg2l
  - Document use for RZ/Five SoC.
* st,stm32-adc
  - Improved calibration support with error logging and a debugfs
    interface to read back the result.
* ti,adc128s052
  - Fix an issue with missing data members in the adc128_of_match table that
    meant all device were being handled as adc128s052 ADCs.

+description: |
+  The AD74115H is a single-channel software configurable input/output
+  device for industrial control applications. It contains functionality for
+  analog output, analog input, digital output, digital input, resistance
+  temperature detector, and thermocouple measurements integrated into a single
+  chip solution with an SPI interface. The device features a 16-bit ADC and a
+  14-bit DAC.

+description: |
+   The ADF4377 is a high performance, ultralow jitter, dual output integer-N
+   phased locked loop (PLL) with integrated voltage controlled oscillator (VCO)
+   ideally suited for data converter and mixed signal front end (MxFE) clock
+   applications.
