IIO: 2nd set of new device support, features and cleanup for 6.11

The big one here is we finally have Paul Cercueil's (and others)
DMA buffer support for IIO devices enabling high speed zero
copy transfer of data to and from sensors supported by IIO (and for
example USB).  This should aid with upstream support of a range of
higher performance ADCs and DACs.

Two merges from other trees
- spi/spi_devm_optimize used for simplification in ad7944.
- dmaengine/topic_dma_vec to enable the DMABUF series.

One feature with impact outside IIO.
- Richer set of dev_err_probe() like helpers to cover ERR_PTR() cases.

New device support
==================
adi,ad7173
- Add support for AD4111, AD4112, AD4114, AD4115 and ADC4116 pseudo
  differential ADCs. Major driver rework was needed to enabled these.
adi,ad7944
- Use devm_spi_optimize_message() to avoid a local devm cleanup
  callback. This is the example case from the patch set, others will
  follow.
mediatek,mt6359-auxadc
- New driver for this ADC IP found in MT6357, MT6358 and MT6359 PMICs.
st,accel
- Add support for the LIS2DS12 accelerometer
ti,ads1119
- New driver for this 16 bit 2-differential or 4-single ended channel
  ADC.

Features
========
dt-bindings
- Introduce new common-mode-channel property to help handle pseudo
  differential ADCs where we have something that looks like one side
  of differential input, but which is only suited for use with a
  slow moving reference.
adi,adf4350
- Support use as a clock provider.
iio-hmwon
- Support reading of labels from IIO devices by their consumers and
  use this in the hwmon bridge.

Cleanup and minor fixes
=======================
Treewide
- Use regmap_clear_bits() / regmap_set_bits() to simplify open coded
  equivalents.
- Use devm_regulator_get_enable_read_voltage() to replace equivalent
  opencoded boilerplate. In some cases enabled complete conversion to
  devm handling and removal of explicit remove() callbacks.
- Introduce dev_err_ptr_probe() and other variants and make use of
  of them in a couple of examples driver cleanups. Will find use in
  many more drivers soon.
adi,ad7192
- Introduce local struct device *dev and use dev_err_probe() to give
  more readable code.
adi,adi-axi-adc/dac
- Improved consistency of messages using dev_err_probe()
adi,adis
- Split the trigger handling into cases that needed paging and those that
  don't resulting in more readable code.
- Use cleanup.h to simplify error paths via scoped cleanup.
- Add adis specific lock helpers and make use of them in a number of drivers.
adi,ad7192
- Update maintainer (Alisa-Dariana Roman)
adi,ad7606
- dt-binding cleanup.
avago,apds9306
- Add a maintainer entry (Subhajit Ghosh)
linear,ltc2309
- Fix a wrong endian type.
st,stm32-dfsdm
- Fix a missing port property in the dt-binding.
st,sensors
- Relax whoami match failure to a warning print rather than probe failure.
  This enables fallback compatibles to existing parts from those that don't
  necessarily even exit yet.
