IIO: 2nd set of new device support features and cleanup for 6.12

Late pull request as I was planing to include another series that
is waiting for a fix to end up in char-misc-next.  That can wait
for next cycle.

Includes one immutable branch merge from MFD to get a necessary header
change.

Usual mix of a few new drivers, additional device support for existing
drivers, new features and a bunch of cleanup across tree.

New device support
==================

asahi-kasei,ak8975
- A few minor fixes as precursors to support for the AK09118 magnetometer
  that is very similar to the already supported AK09112
awinic,aw96103
- New driver for this capacitive proximity sensor.
x-powers,axp202
- Add support for the axp717 (including merge of MFD immutable branch).
sophgo,saradc
- New driver for this SOC ADC.

Features
========

adi,ad4695
- Add calibration support.
bosch,bmi323
- Ensure device is in lowest power state on suspend.

Cleanup and minor fixes
=======================
treewide
- Start to standardize formatting of id tables (ADC drivers done so far).
adi,ad5449
- Drop platform data support as long unused in upstream kernel.
bosch,bmc150
- Use fwnode_irq_get_by_name() in place of of_ variant.
- Use ACPI_HANDLE() to get the handle directly rather than via
  ACPI_COMPANION()
google,cros_ec_mkbp_proximity
- Include mod_devicetable.h instead of broader of.h
mirochip,mcp320x
- Drop vendorless compatible entries as not needed for backwards
  compatibility and should not be used in new boards.
st,lsm6dsx
- Use iio_read_acpi_mount_matrix() helper instead of open coding the
  same.
- Drop some unnecessary dev_fwnode() calls to check if a fwnode is
  available.  All the calls made handle this anyway.
xilinx,ams
- Use device_for_each_child_node_scoped() to avoid manual release of
  fwnode handle.

tools,generic-buffer
- Handle failure to allocate trigger name.
- Cleanup .*.cmd files if present.

+  Awinic's AW96103/AW96105 proximity sensor.
+  The specific absorption rate (SAR) is a metric that measures
+  the degree of absorption of electromagnetic radiation emitted by
+  wireless devices, such as mobile phones and tablets, by human tissue.
+  In mobile phone applications, the proximity sensor is primarily
+  used to detect the proximity of the human body to the phone. When the
+  phone approaches the human body, it will actively reduce the transmit
+  power of the antenna to keep the SAR within a safe range. Therefore,
+  we also refer to the proximity sensor as a SAR sensor.
