Why is this chip-specific enough to be called "t104xsi", but not 
chip-
specific enough to just go directly into t1040si-post?

T104x platform share the same calibration data.

Which t104x are you referring to that doesn't use t1040si-post.dtsi?  
Plus, given the numbering scheme it's always possible that a new t104x 
comes out that has little to do with existing t104x.
