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.
