iio: orientation: hid-sensor-rotation: fix quaternion alignment

Browse source

Restore the alignment of sampled_vals to 16 bytes by using
IIO_DECLARE_QUATERNION(). This field contains a quaternion value which
has scan_type.repeat = 4 and storagebits = 32. So the alignment must
be 16 bytes to match the assumptions of iio_storage_bytes_for_si() and
also to not break userspace.
