Alexandru Ardelean d372e5a19a iio: accel: adxl345: convert probe to device-managed functions
This driver has two parts, one for i2c and one for spi, since the chip can
operate with both wire protocols.

The core file has a common adxl345_core_remove() function which puts the
chip into a powerdown state. This can be implemented with a
devm_add_action_or_reset() hook.

Doing that means we can register the IIO device with
devm_iio_device_register() and get rid of the adxl345_core_remove()
function.

The dev_set_drvdata() call can be removed as there is no other user of this
private data anymore.

Alexandru Ardelean 6b8471e460 iio: adxl345: move null check for i2c id at start of probe
Fixes ef89f4b96a ("iio: adxl345: Add support for the ADXL375").

This was found via static checker.
After looking into the code a bit, it's unlikely that there will be a NULL
dereference if the `id` object in that specific code path.
However, it's safe to add a NULL (paranoid) check just to make sure and
remove any uncertainties.

Lars-Peter Clausen ef89f4b96a iio: adxl345: Add support for the ADXL375
The ADXL375 is fully register map compatible to the ADXL345 (including the
device ID register returning the same value ...).

The only difference is the resolution of the acceleration sensor. The
ADXL375 can measure up to +-200g of acceleration.

Eva Rachel Retuya 5170512cf6 iio: accel: adxl345: Split driver into core and I2C
Move I2C-specific code into its own file and rely on regmap to access
registers. The core code provides access to x, y, z and scale readings.
