iio: accel: add ADXL380 driver

The ADXL380/ADXL382 is a low noise density, low power, 3-axis
accelerometer with selectable measurement ranges. The ADXL380 supports
the +/-4 g, +/-8 g, and +/-16 g ranges, and the ADXL382 supports
+/-15 g, +/-30 g and +/-60 g ranges.
The ADXL380/ADXL382 offers industry leading noise, enabling precision
applications with minimal calibration. The low noise, and low power
ADXL380/ADXL382 enables accurate measurement in an environment with
high vibration, heart sounds and audio.

In addition to its low power consumption, the ADXL380/ADXL382 has many
features to enable true system level performance. These include a
built-in micropower temperature sensor, single / double / triple tap
detection and a state machine to prevent a false triggering. In
addition, the ADXL380/ADXL382 has provisions for external control of
the sampling time and/or an external clock.

Important things to be added include the double-tap, motion

In addition to its ultralow power consumption, the ADXL367

It includes a deep multimode output FIFO, a built-in micropower

iio: accel: bmc150: Add support for BMC156

BMC156 is another accelerometer that works just fine with the bmc150-accel
driver. It's very similar to BMC150 (also a accelerometer + magnetometer
combo) but with only one accelerometer interrupt pin. It would make sense
if only INT1 was exposed but someone at Bosch decided to only have an
INT2 pin.

Try to deal with this by making use of the INT2 support introduced
in the previous commit and force using INT2 for BMC156. To detect
that we need to bring up a simplified version of the previous type IDs.

Note that unlike the type IDs removed in commit c06a6aba6835
("iio: accel: bmc150: Drop misleading/duplicate chip identifiers")
here I only add one for the special case of BMC156. Everything else
still happens by reading the CHIP_ID register since the chip type
information often is not accurate in ACPI tables.

iio: accel: bma180/bmc150: Move BMA254 to bmc150-accel driver

Commit c1d1c4a62db5 ("iio: accel: bma180: BMA254 support") added
BMA254 support to the bma180 driver and changed some naming to BMA25x
to make it easier to add support for BMA253 and BMA255.

Unfortunately, there is quite some overlap between the bma180 driver
and the bmc150-accel driver. Back when the commit was made, the
bmc150-accel driver actually already had support for BMA255, and
adding support for BMA254 would have been as simple as adding a new
compatible to bmc150-accel.

The bmc150-accel driver is a bit better for BMA254 since it also
supports the motion trigger/interrupt functionality. Fortunately,
moving BMA254 support over to bmc150-accel is fairly simple because
the drivers have compatible device tree bindings.

Revert most of the changes for BMA254 support in bma180 and move
BMA254 over to bmc150-accel. This has the following advantages:

- Support for motion trigger/interrupt
- Fix incorrect scale values (BMA254 currently uses the same as
BMA250 but actually they're different because of 10 vs 12 bits
data size)
- Less code than before :)

BMA250 could be potentially also moved but it's more complicated
because its chip_id conflicts with the one for BMA222 in bmc150-accel.
Perhaps there are also other register differences, I did not investigate
further yet (and I have no way to test it).

iio: accel: bmc150: Clarify combo modules in Kconfig

The Kconfig option currently says that all Bosch accelerometers
supported by the bmc150-accel driver are combo chips with both
accelerometer and magnetometer. This is wrong: actually only BMC150
is such a combo. The BMA* variants only contain an accelerometer
and the BMI055 actually is a accelerometer + gyroscope combo.

Clarify this in the help text and also make the list of supported
variants complete and sorted for consistency.
