iio: accel: adxl345: simplify measure enable 

Simplify the function to enable or disable measurement. Replace the
separate decision logic and call to regmap_update_bits() by a single
call to regmap_assign_bits() taking a boolean argument directly.

This is a refactoring change and should not impact functionality.
