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.
