iio: imu: st_lsm6dsx: make IIO_CHAN_INFO_SCALE shared by type
in_accel_x_scale, in_accel_y_scale and in_accel_z_scale are always
the same. The scale is still defined to be in "info_mask_separate".
Userspace (iio-sensor-proxy and others) is not used to that and only
looks for "in_accel_scale" for the scaling factor to apply.
Change IIO_CHAN_INFO_SCALE from being separate in all channel to be
shared by type.
This removes in_accel_x_scale, in_accel_y_scale and in_accel_z_scale and
makes available in_accel_scale.
This is an ABI change, but hopefully in the 'no one will notice'
category. The cleanup in interface is worth the small risk that
there is a custom script out there somewhere that this will break.
