iio: core: Add IIO_EV_INFO_SCALE to event info

Browse source 
Implement support for IIO_EV_INFO_SCALE in the internal enum
iio_event_info to allow proper ABI compliance.

This allows drivers (like the ADXL345) to expose event scale
attributes using the standard IIO ABI rather than manual
device attributes.
