iio: add modifiers for linear acceleration

Add IIO_MOD_LINEAR_X, IIO_MOD_LINEAR_Y and IIO_MOD_LINEAR_Z modifiers to te
IIO core, which is preparatory for adding the Bosch BNO055 IMU driver.

Bosch BNO055 IMU can report raw accelerations (among x, y and z axis) as
well as the so called "linear accelerations" (again, among x, y and z axis)
which is basically the acceleration after subtracting gravity and for which
those new modifiers are for.
