Subject: [PATCH v2 0/4] iio: accel: adxl345: Add event scaling and doc fixes

This series addresses ADXL345 driver non-compliance with the IIO ABI
for event thresholds, following feedback from Jonathan Cameron on v1.

Core Changes: During development, I noticed IIO_EV_INFO_SCALE was missing
from the internal IIO core. I've added this constant to the iio_event_info
enum to allow proper ABI compliance. I would appreciate a sanity check on
this infrastructure change.

Testing: This series is compile-tested only, as I do not have access to
physical hardware. Implementation is based on the ADXL345 datasheet.

Changes since v1:
- Added core infrastructure for IIO_EV_INFO_SCALE.
- Implemented event scaling (0.612915 m/s2) for ADXL345.
- Fixed technical math/decimal errors in existing documentation.
- Cleaned up grammar and pluralization issues in .rst file.

Many thanks to Jonathan Cameron for the detailed guidance on v1.
