iio: cros_ec: Add sign vector in core for backward compatibility
To allow cros_ec iio core library to be used with legacy device, add a
vector to rotate sensor data if necessary: legacy devices are not
reporting data in HTML5/Android sensor referential.
Check the data is not rotated on recent chromebooks that use the HTML5
standard to present sensor data.
