First set of new device support, features and cleanups for IIO in the 4.21 cycle

Along with the headline feature of 5 new drivers, we have the
substantial addition of auxilliary sensor support on the lsm6sdx
parts for ST. There has also been a good set of staging cleanup
in this period with more underway.

An ever increasing number of devices supported with just a new
ID which is a good sign that at least some manufacturers are
continuing to stabilise their interfaces.

New device support,
* ad7124
- New driver supporting Analog Devices' ad7124-4 and ad7124-8 parts
with the inevitable DT binding.
* ad7949
- New driver supporting Analog Devices' ad7949, AD7682 and AD7689 ADCs.
* rm3100
- New driver supporting PNIs RM3100 magnometer with bindings and
vendor prefix.
* ti-dac7311
- New driver supporting DAC7311, DAC6311 and DAC5311 TI DACs, with
DT bindings.
* vcnl5035
- New driver supporting the light sensor part of the VCNL4035, with
DT bindings

Features,
* bindings
- Add a generic ADC channel binding as we keep reinventing this
wheel.
* adc128s052
- Add IDs for additional pin compatible parts.
- Add APCI ID seen on E3940 UP squared boards.
* ad_sigma_delta
- Allow for custom data register overiding default.
* kxcjk1013
- Add KIOX0009 ACPI ID as seen on the Acer One 10.
* lsm6dsx
- Rework leading to...
- External sensor support using the built in I2C master.
- Initial support for a slave lis2mdl magnetometer.
* meson-saradc
- Add temperature sensor support and bindings.
* st_magn
- New ID for lsm9dsl_magn with bindings
- New ID for lis3de accelerometer
* tpl0102
- Add supprot for IIO_AVAIL_RANGE to report the range available
from this device to userspace and in kernel users.

Cleanups and minor fixes
* tools
- Allow outside specification of CFLAGS
* ad2s90
- Handle and spi_read error.
- Handle spi_setup failure
- Drop a pointless assignment.
- Prevent a potentail race by moving device registration to after
all other setup.
- Add missing scale attribute.
- Add a sanity check on channel type before trying to read it.
* ad2s1210
- Move to modern gpio descriptors.
- Drop a gpioin flag which made no sense as far as we can tell.
- Add dt table (bindings doc to follow when this is ready for
moving out of staging).
* ad5933
- Drop camel-case naming of ext_clk_hz.
- White space fixes.
* ad7150
- Local variable to shorten overly long line.
- Alignment and line break fixes.
* ad7280a
- Handle an error path that was previously ignored.
- Use crc8.h to build the crc table replacing custom code.
- Avoid unecessary cast.
- Power down the device if an error happens in probe
- Use devm routines to simplify probe and remove.
* ad7606
- Alignment fixes.
* ad7780
- This worked as long as by coincidence an uninitialized value
was 0. Lets not rely on that.
- Ensure gain update is only used with the ad778x chips that
actually support it.
- Tidy up pattern mask generation.
- Read regulator when scale is requested (which should be infrequent)
as it might have changed from initialization.
* ad7816
- Move to modern gpio descriptors
- Don't use a busy_pin for ad7818 as there isn't one.
- Ensure RD/WR and CONVST pins are outputs (previously they
were brought up as inputs which doesn't seem to make any sense)
- DT id table.
* adc128s052
- SPDX
* adt7316
- Alignment fix.
- Fix data reading. When using I2C the driver never actually
used the value read. This has been broken a very long time
hence no rush to fix it now + the driver is undergoing a lot
of cleanup.
- Sanity check that the i2c read didn't fail to actually read
anything.
* dpot-dac
- Mark a switch full through with slightly different text so that
gcc doesn't warn on it.
* gyro-adc
- Fix a wrong file in the MAINTAINERS entry and add binding doc to the
listed files.
* ina2xx
- Add some early returns to clarify error paths in switch.
* lsm6dsx
- MAINTAINERS entry.
* max11100
- SPDX
* max9611
- SPDX
* mcp4131
- use of_device_get_match_data in preference to spi_get_device_id
approach.
* rcar-adc
- SPDX
* sc27xx
- Add ADC conversion timeout support to avoid possible fault.
* ssp_sensors
- Don't free managed resources manually.
* st-magn
- Add a comment to avoid future confusion over when to use -magn
postfix (on multi chip in package parts)
- Add BDU register for LIS3MDL where it seems to have been missed.
* st-sensors
- Minor spelling, grammar etc fixes.
* tpl0102
- Use a pointer rather than an index of an array to improve conciseness.
