As it has been already done for other st sensors in 'commit 9049531c91b4
("iio: accel: st_accel: inline per-sensor data")', get rid of some
defines and just open code the values into the appropriate struct
elements since the semantic meaning is inherent in the name of the
C99-addressable fields and there is no reason to duplicate the code

Nice cleanup.
Applied to the togreg branch of iio.git and pushed out as testing for
the autobuilders to play with it.

thanks,
