This is basically what gets translated to sd_factor_table and I removed
the extra entries 25..31. Actually I also dropped the 24th one, since
that would give us an odd number of items, although I'm not quite sure
this is a bug in the xapp-le code or the HW is really supposed to work
like that.

In my datasheet I can see the factor values till 24. So let's remove the
entries from 25-31.

I got an updated datasheet and I confirm 24 is a valid selector. Applied
the correction in v2:
